Trunk or Treat Ideas That Draw a Crowd in St. Louis

The trunk or treat ideas that draw the biggest crowds are decorated trunks with a clear theme, one anchor attraction that keeps families on-site after the candy runs out, a loop layout that keeps foot traffic moving in one direction, and a published rain plan. Themes people line up for include a movie night trunk, a candy shop, a fishing hole, a bug-out camp site, and a sports tailgate. Plan two to three pieces of candy per child per trunk, and set the event on a weeknight or early Saturday evening in mid-to-late October.

"This gaming entertainment was a big hit at our Community Give Back day at our church." That's Mary Love, and it points at the thing most trunk or treat committees find out the hard way. The trunks bring people in, and something else has to keep them there.

We run these events across St. Louis and Metro East Illinois every fall, for churches, schools, PTOs, and neighborhood associations. What follows is what we watch work and not work from the parking lot.

What a trunk or treat is

A trunk or treat is a Halloween event where cars park in a lot, open their trunks, decorate them around a theme, and hand out candy to kids who walk from car to car. Churches and schools host most of them, because a lit lot with adults everyone knows is a safer, warmer, faster version of walking a neighborhood, and it takes about 90 minutes instead of a whole evening.

Trunk themes that people stop for

The trunks that get photographed have one idea carried all the way through, and they cost less than the ones that try to do everything. Twelve that work:

Drive-in movie night. A sheet across the hatch, a projector or a tablet playing a cartoon, popcorn boxes for the candy.
Candy shop. Striped awning made from a plastic tablecloth, jars of candy, staff in aprons.
Fishing hole. A blue tarp, cardboard fish, and a pole with a clothespin, kids "catch" their candy.
Camp site. A small tent behind the car, battery lanterns, a fake fire, s'mores kits handed out.
Barnyard. Hay bales, a wagon wheel, stuffed animals, and a farmer costume.
Under the sea. Streamers hung from the hatch as kelp, blue lights, kids walk under it.
Sports tailgate. Team colors, a mini hoop or a bean bag toss, cups and pennants.
Space station. Foil, black lights, glow sticks handed out with the candy.
Construction zone. Cones, caution tape, hard hats, toy trucks in a bin of "dirt."
Bakery. Chef hats, a pastry case built from a cardboard box, candy in bakery bags.
Storybook. One book everybody knows, with the pages blown up and taped across the trunk.
Video game world. Pixel blocks cut from cardboard, coins hanging on fishing line, a controller prop.

Give people the theme list eight weeks out and let them claim one, first come. Two identical candy shops next to each other is the most common preventable disappointment at these events.

The one decision that changes the size of your crowd

Trunks take about 20 minutes to walk. After that, families either drift to their cars or stay, and what they do depends entirely on whether there is a reason to stay. An anchor attraction is that reason, and it is the difference between 150 people and 400.

What we see hold a lot after the candy:

A game truck. Kids rotate through in groups while parents talk in the lot. Ours is climate-controlled and runs on its own generator, so it does not need your building's power and it stays warm when the sun drops.
Laser tag on the grass or the far end of the lot. Best for the 9-and-up crowd who are too old to be excited about candy and too young to be dropped off somewhere else.
An inflatable obstacle course. The younger siblings burn off the sugar, which every parent there will quietly thank you for.
Virtual reality under a canopy. A line forms and does not break, and it photographs better than anything else at the event.

Amanda Crouch, a PTO president who books us for a school fall festival, put the repeat-request part plainly: "Kiddos request their laser tag and inflatable obstacle course."

Games and activities beyond the candy

Low-cost stations that fill the gaps between trunks, run by one volunteer each:

Pumpkin ring toss with plastic rings and painted milk jugs
A costume parade at a fixed time, announced twice, with a photo backdrop at the end
Donut on a string, which produces the best photos of the night
A cake walk, if you have a group that will bake
Flashlight tag in a roped-off grass area once it gets dark
A trunk-decorating vote, with a printed ballot and a prize announced at the end, which is also what keeps decorators there until closing

Layout, timing, and candy math

Set the trunks in a horseshoe or a single loop so families move one direction and nobody backtracks through the line. Put the anchor attraction at the far end, so the whole lot gets walked to reach it, and put food in the middle where the line will not block a trunk.

On quantities, plan two to three pieces per child per trunk, and count on more kids than RSVP. Twenty trunks at 200 kids is a lot of candy, so ask each trunk host to bring their own bag count and keep a backup case at the check-in table. On timing, 5:30 to 7:00 on a weeknight or 4:00 to 6:00 on a Saturday in mid-to-late October, before the time change takes the light away.

The rain plan, written down before anyone asks

Late October in St. Louis will hand you a 45-degree drizzle at least one year in three, and the events that survive it are the ones that decided in September. Pick your call time, usually noon the day of, name the person making the call, and say where it gets posted.

Ask your attraction vendors what they do in weather before you sign. We move indoors to a gym or a fellowship hall when a space is available, and the game truck itself is heated, which is why it tends to be the last thing running at a cold event. Emily Mullin, after a school event of ours that got rained on: "Due to rain we had to move inside and Me 2 You flawlessly adjusted. The kids had a fantastic time."

An eight-week timeline

8 weeks out. Lock the date and the rain date. Book any attraction now, because October Saturdays go first and they go early.
6 weeks out. Publish the theme list and open trunk sign-ups. Ask for a certificate of insurance from any vendor and put it in the file.
4 weeks out. Recruit volunteers by station, not by shift. People say yes faster to "run the ring toss" than to "help out."
3 weeks out. Promote it. A neighborhood group post, the school newsletter, and a flyer home in backpacks reach three different families.
2 weeks out. Walk the lot and draw the map, including where a truck or a trailer parks and how it gets out.
1 week out. Confirm every trunk, send the map, and confirm arrival times with vendors.
Day of. Trunks arrive 60 minutes early, attractions 60 to 90 minutes early, and one person owns check-in so nobody wanders the lot looking for their spot.

Four mistakes we watch committees make

Booking the attraction last. By late September the good October dates are gone. It is the first call, not the last.
No parking plan for the vendor. A game truck needs about 55 feet to park and a clear path in and out. Find that spot in advance, and cone it off that morning.
Ending in the dark with no lighting. Rent or borrow light towers, or end earlier. A dark lot empties fast.
Assuming the vendor brings power. Ask. Ours runs on its own generator, and plenty of setups do not, which is a bad thing to learn at 4:45.

Why October fills up before you expect it to

Search interest for trunk or treat ideas around St. Louis runs roughly seven times higher in October than the yearly average, according to Google's own keyword volume data, and it starts climbing in September. That curve is also the booking curve, and it is why the churches who book us in August get their first-choice Saturday and the ones who call in October are choosing between the leftovers.

If you want the parking lot handled, we bring the attraction, a named host who runs it start to finish, and a team that has done this in the rain. You get to walk your own event and talk to the people who came, which is the whole reason you volunteered for it.

Frequently asked questions

What is a trunk or treat?

A trunk or treat is a Halloween event where cars park in a lot, decorate their open trunks around a theme, and hand out candy to kids who walk from car to car. Churches and schools host most of them because a lit, contained lot staffed by familiar adults is safer and faster than walking a neighborhood, and it usually runs about 90 minutes.

What are the best trunk or treat themes?

The themes that draw the longest lines carry one clear idea all the way through: a drive-in movie night, a candy shop, a fishing hole where kids catch their candy, a camp site with a tent and a fake fire, a barnyard, under the sea, a sports tailgate, a space station, a construction zone, a bakery, a storybook, and a video game world. Publish the list early and let trunks claim a theme first-come so you don't end up with duplicates parked side by side.

How much candy do you need for a trunk or treat?

Plan two to three pieces of candy per child per trunk, and count on more kids attending than RSVP. Ask each trunk host to bring their own supply and keep a backup case at the check-in table, since a trunk that runs out early tends to pack up and leave.

What should you add to a trunk or treat besides candy?

Families walk the trunks in about 20 minutes, so an anchor attraction is what keeps them on-site after that. A game truck, laser tag, an inflatable obstacle course, or virtual reality all hold a crowd, alongside low-cost volunteer stations like a ring toss, a costume parade at a set time, donut on a string, and a trunk-decorating vote announced at the end.

How far in advance should you book a trunk or treat attraction in St. Louis?

Book eight weeks out, in August or very early September. Search interest for trunk or treat ideas in the St. Louis area runs about seven times the yearly average in October, and October Saturdays are the first dates to fill. Me 2 You Game Truck takes fall bookings across St. Louis and Metro East Illinois, with no deposit required for churches and schools.

What happens to a trunk or treat if it rains?

Decide in advance: set a call time (noon the day of works well), name the person making the call, and say where the decision gets posted. Ask attraction vendors what they do in weather before you sign. Me 2 You moves indoors to a gym or fellowship hall when a space is available, and the game truck is heated and runs on its own generator, so it keeps going in cold or wet weather.
