We live on a quiet little street and really like our neighbors. As there are lots of young children, Halloween is a very popular holiday. And we have a really nice tradition that involves the whole neighborhood.
Each year, we find a bowl out front wih Halloween treats. This year's bowl had Halloween socks, Halloween cake mix in black and orange colors (with decorations), candy corn and some other candies. There was also a Halloween poem and a little decorated sign that says "BOO."
Your role is to refill the bowl with treats and leave it for another neighbor. You also make a copy of the BOO sign and put it on your front door, to show you've gotten your treats. It ends up looking like this:
All in all, a very neighborly tradition.
