Get Involved

Trunk-or-Treat Hosts: All of our Trunk-or-Treat spaces are booked. If you would like to be added to the waitlist in case a space opens up, complete an online application to express your interest.

The event targets more preschool and elementary age kids. Your parking lot space can include a vehicle with candy in the truck but it doesn't have to. Hosts can set their parking lot space up however they would like. We highly encourage hosts to wear a costume.
