We climbed fences, jumped over them & ran through all of the yards-- no one cared. We were just being kids, and, unlike kids today, NONE of us were even slightly plump -- all that running, climbing and jumping was hard work.
Once we knew someone didn't care if we went in a fenced yard (and I can't remember one we couldn't go in:), we did that too. I really feel for kids now a days.
