I went Trick or Treating with the kids. They wanted to go with 2 friends. One thing led to another and we wound up with about 9 kids/5 families. They had a blast. I think they had as much fun divying up and trading candy afterwards as they did going door-to-door. My 3 year-old was running the entire time (last year I carried him the entire time).
My wife stayed home with another (hot) mom to hand out candy. Unfortunately she said it was kinda slow. Out of our block with 21 houses, only 3 of us have little kids.
