Even back in the day, we only used to get 15-20. They were ALL kids we knew, and we could almost set our clocks by them. One little boy's dad was a drunk, and his mom had to do barn chores before she could take him trick-or-treating. We always told her that if she saw even one light on, Jason could stop--didn't matter if it was ten or eleven o'clock.

All those kids grew up, and the numbers dwindled to maybe half a dozen, spread from 5 to 8 o'clock, so we had to be on alert all evening. It's too hard for us now (split-level, so up and down stairs to the door) and our driveway isn't really safe for those unfamiliar with it. So we pull our shades and keep the lights out. (And eat the candy)
