jumping garbage cans with our bikes. We lived on a big hill that turned down hill into a flat parking lot. We would get as many garbage cans (The old galvanized metal ones) as we could find, build a ramp with a piece of plywood and everyone would get a turn jumping over 5, then 6 then 7 and keep going until only one guy was left, or our rims were too bent to ride anymore.
playing wiffleball we would wrap the bat in electrical tape and put small rocks in the ball itself. every pitch was a knuckball.
last summer a buddy bought a new house. After helping him move we were hanging out drinking and wanted to do something. His Bag boards (corn hole) were at his old house over an hour away and we were in no condition to drive, so walking around in his garage I found a set of Jarts ..the originals..not the crap they sell now. Stole his daughters hula hoops, made a smaller ring out of rope... game was 21...1 point in the big ring...3 in the small ring...win by 2..go over and go back to 11..after a 30 rack a game would last like 2 hours... but we had a ball
