Back in my day, we played outside on days off. We once went to a vacant lot in the neighborhood, dug up a ton of dirt and put a box over the hole with a "door" cut into it to make a "fort". I grew up on a canal and we swam in it. We also climbed trees.
I was a heavy, clumsy kid. When we ran I always fell and got holes in the knees of my pants, so my mother would make shorts out of them. I was so frustrated that I couldn't wear bellbottoms because I would have to buy Huskies and the bell would need to be cut off. Then I went through puberty and a diet and graduated high school at 135 pounds. Wore all the bellbottoms I wanted!
My only real indoor activity was watching TV and playing 45's on my record player. I used to buy the latest songs at the Singer store in the mall. Why a sewing store would sell records was beyond me, but they had a good selection. I never missed an episode of Dark Shadows in the afternoon. I Dream of Jeannie, Bewitched, The Beverly Hillbillies and Laugh In were also staples.
I did have some "hooligan" friends, and in Junior High we skipped school and hung out all day at a 7/11. There was no fun in it, but kids do stupid things.
