I got into skateboards in 1977 when it first became a craze. The boards then were a bit hit and miss. i did buy one I made up of parts around 10 years ago. I still have it but not ridden it much since I hurt myself on it. It wasn't too serious but it hurt like a bar-steward for a few days. I attempted to slide down a hand rail, not a steep metal one but a wooden one by a path. The top had been plained flat and it had a gentle decline on it. This was at my friends kids school's open day so there were people everywhere. My mate held the board while I climbed up on the rail, the plan was to find my balance and slide down. Over confidence got the better of me and fell straight off. The board went to the floor vertically and i fell onto the end of the deck, just missing my bottom rib. The grip tape made a nice mess of my skin. It was funny though, for the crowd watching! I did see the funny side. Born again anything you did as a kid can mess you up though so go carefully.
I used to do rollerskating at the southbank by the Thames a lot. That was a great place to hang out.
Motorcrossing, a bit of surfing, Ski-ing and a few extreme sports years back.
