Here, if you practice on Halloween, you will miss all the legal hours to trick or treat-most of our teams practice from 6:00-8:00 or 6:00-8:30. Add that pretty much the minimum drive to go anywhere is 30 minutes and there's no time to ToT. Most suburbs limit ToT to 8:00 or 9:00, and if you go before you need to leave for practice, no one would be home!
I'm very glad the gym is closed on Halloween. We have a themed practice the Sunday before, and have a Trunk or Treat/party as a gym bonding activity after practice on Sunday.
