My buddy used to do backside 180 slides into a concrete quarter pipe at the park that was 4 feet. He'd start sliding on his back wheels on the deck and slide his wheels and trucks over the coping and stay on his back wheels sliding into the quarter. I saw him a couple of years b4 that do a nollie cab on a steep vert wall. kamakazie skateboarder. Another time I saw some little young girl who was at the park with a skateboard but didn't look like a skateboarder and she was barefoot and had her sisters with her. Anyway she was managing feeble spine tranfers (6ft to 4ft), -I was pretty blown away by that, I don't think she knew what feeble stalls were, it was just what she learned after droping in by the look of it. She worked her way up to it. Anyway, inspiring skateboarding.
