Our neighborhood is VERY old fashioned. It is lined with sidewalks and there are lots of kids around. We have a park 2 blocks from us and kids are everywhere. I have 2 little girls within 6 months for my DD3 within a block. There are kids my son's age within 2-3 blocks, but unfortunately he hasn't really clicked with any of the very close kids. Some parents in this area are very relaxed about letting the kids run around on their own. I'm not there yet.
