Trunk or Treat is a service event geared toward UMSL families and the surrounding community. The attendants will enjoy various activity and informational booths, followed by “trunk-or-treating,” which means they go from trunk to trunk getting treats! UMSL student organizations, departments/offices, and individuals can provide trunks (including treats), or create an activity booth. Started in 2010, this program has grown from 75 children to almost 300 attending. Prizes for the best trunk and costume (student, staff, or faculty member) are on the line.
