Pick up game of kickball and tree climbing

I remember so many games growing up in my corner of the world in Salina, KS on Highland Ave. of pick up games of kickball, baseball, and tree climbing.  On my block there were about 10 house and we all had kids about the same age and could knock on each other's door to play.  My kids are getting that same experience here.  Most of the kids on our street are about the same age and love to play outside with each other.  It is fun to see the games of kickball and tree climbing that come about everyday around here.
