All was going so well, the sun was shining, not a cop in sight, and I had put a smaller front sprocket on for some extra zip. You may have realised by now that all the right ingredients to do something silly have been mentioned, but wait there is more, I WAS WEARING NO PROTECTIVE CLOTHING - NOT EVEN A HELMET!!!!! I had just come round the bend and with that lower gearing the front just wanted to come up. I was all silly grins and just had to give it a handfull, loose gravell and bang over it went, I landed on my left ar$e cheek and the bike landed on me. FAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAARK!!!!!!!!!!!!!! it hurts, thank the chemist for Voltaren, because now I look like michael Jacksons Skin treatment in reverse. ( Well half my butt does anyhow) Worse still I had an audience, but on the fortunate side they know me and have willingly accepted the foolish things that I have done in the past, so were not at all surprised by the 'funniest home videos production that I had just pulled. Financially I have some cosmetic repairs to do, but that is about all, and I think I have been banned from riding my son's fast 50 around the back yard in the future.
