We have tons of kids everywhere, it's fun passing out candy. We usually sit out on the porch with the dogs, I'll drink too much and start witty banter with the parents while my wife passes out candy to little kids in superhero costumes. If football is on I have that playing on a laptop outside.
After all the kids have gone home I'll stand around outside on the street with my neighbors and generally BS. I'm not a cop but we have 3 on my street (one of which lives directly across from me), so no real issues seem to ever present themselves.
