Trunk or treat is catching on big-time. When I was a lad a local school did similar and called it Halloween Frolics. They'd have bob for apples, live music and stuff but then one year they just didn't do it anymore.
My friends and I preferred the freedom of roaming around without chaperone supervision so we could explore our abilities to partake in hyjinx like burping and farting. Nothing too crazy, just good clean fun like the 4th graders we were. Today with all the crazy taking place the trunk or treat thing is way more practical.
Good man Scout.
