After reading all the many and varied threads here about peoples crashing their bikes due to many and varied causes totally out of their control, I was feeling a bit left out No longer however.Today I took my bike out for a bit of a spin in the hills.Yeah, the weather wasn't great, and I haven't been out riding for a while, so I'm a bit rusty on it I guess. Anyway I'm hammering down a reasonable sort of hill, at a pretty respectable pace, and strike me dead, this rock just jumps out in front of me. Well, that's my excuse. Could have been target fixation, but lets not go there. Anyway, over the bars I go, head butting a log on the way, cracking my helmet on the way. Layed there for a minute gathering my wits and breath, wiggled all extremities to check for proper functions and all seemed well.Couple of dudes pulled up to see if I was okay, which I seemed to be if you don't count the blood pissing out of my knee and the trickle from my hand, or the great lump appearing on my cheekbone. Time for a new helmet mate says one of them.Bike doesn't seen too damaged offers another. Yeah, says I, lucky I landed on my head, or there could have been a serious injury. ****in mountain bikes. Dangerous things they are.Government should ban them I reckon. Or at least bring in some rules and regulations to stop people hurting themselves. Ha.
