Aggie, my last neighborhood was like yours. We lived in a town that didn't have sidewalks (most towns here don't) so parents drove their kids to our development of 25 houses. Plus, we did have a lot of kids in the neighborhood. The second to last year, I gave out 11 bags of candy and ran out! Then, finally, there was a slight decrease, due only to the fact that some of the kids were now in high school and no longer went out.
It was crazy!
