Our town's sanctioned Trick or Treat time is 5:30-7:30 tonight. Used to be 6-8, not sure what prompted the change this year. It was still light out at 5:30, but now it's dark out.
Our town is really safe and classy about it though. Every rescue vehicle in the town is out with it's lights flashing, roving slowly from street to street to provide just enough light to keep things safe without being restrictively bright (like having the Trick or Treat the Sunday before Halloween from 3-5 like the town I grew up in did).
It really is quiet out there. I hope there's a good push in the last hour.
