Yeah me too! I had the occasional swimming lesson once per week or something but other than that, if the weather was good, you'd find me and all the neighborhood kids running around playing tag or riding our bikes everywhere. I grew up at a co-op so all of the houses were close together and there were a lot of families and other kids my age.

I think the number one thing you can do for your kid is to live in a neighborhood with lots of other kids.
