I left a bunch of skin on one of the water slides at Action Park...there were 'seams' in the water slide tubes where the pieces attached, and as I was sliding down I got a good skin scraping on my left ass cheek. It ruined my day and I had a scab the size of a softball for weeks.
That place was the best. I fucking clobbered another kid on Surf Hill. He took his turn before me and lingered a little too long instead of getting out of the way and I sent him fucking flying when I crashed into his legs.
