Out door games we played.

All the regular sports. A few, not nearly all.
The favorites.....
Baseball in Chi was either hardball or 16" Clincher softball, which aren't so soft new. Half way through the game ya' needed a new ball.
Fast pitching (rubber ball the size of a hard ball) with the strike zone drawn on walls. Usually 2 on a side but a lot of times 1 per side.
Fence. Divided into 2 teams and ya' had to make it to the opposite school yard fence without being tagged by the opposition. If tagged you played for the opposition till all were caught.
Ditch. Another 2 team thing covering a city block or less after dark. You could hide anywhere ya' dared except inside of something. There was one kid we could never find and always had to call him in. He finally told us his spot. An alley telephone pole above the street light and phone lines but below the electric.
Fishing and smelting on the lake by Meigs Field and Planetarium.
A lot of biking. Lol, Something one never forgets. It wasn't too long after I becoming over confident on two wheels that I T-boned a man's car door while he was west bound on 35th st. I came pretty close that day!
Oh yeah, loved making choppers. We would saw off a old pair of forks and have them welded on to the good forks, bam, instant chopper!!
What? Welded? We just banged them on and hoped for the best!
I built my first 10 speed out of old used scrounged parts and 26" frame I pulled from someones garbage. Sold it for 10 bucks when I got mt first car.
