We routinely have 2,500 to 3,000 kids in our neighborhood every Halloween. Our neighborhood is safe, relatively affluent, with narrow lots (60 feet wide) and adjacent to/not far from less safe/less affluent neighborhoods. Perfect for maximizing candy volume.8
So every Halloween we’re inundated, and that’s fine, and everyone has a good time, and there’s so many people that vendors set up food stalls at two or three junctions in the neighborhood for that night.
I don’t mind any of that, kids and their parents have fun. The only thing that bugs me is that I can’t walk my dog for a week afterward because the families drop so many candy wrappers on the ground. And Labrador Retrievers looooove old candy wrappers, and anything else they can get their mouths around.
