I was greatly looking foward to my ride today, seeing how it would be my last for a little while until I get moved into college and get settled. So I am biking along a nice shoulder, more than enough clearance from the road and for me to bike in peace. I come to a downhill and I crouch down to pick up some speed, not long after the hill flatened out I looked ahead of me and a large rock was right in the middle of the shoulder and it was already too late for me to react. I hit the rock dead on with my front tire, and beleive it or not hit it dead on the back one as well. By this time I was going about 28-30mph, I went completly out of control and was went swirving all over the shoulder trying to regain control, I ended up flying into a small ditch on the side of the road and fell clear off my bike. My bike is "alright" nothing major, the chain just needs to be put back on because its in a way that this newbie can't even understand, both tires are flat, the handle bars arn't really bent, but when I hold the bike upright the handle bars are off to the side, a matter of straigtening them out really, nothing major. So I began on my 15 mile walk home, about 20 minutes later a Massachusetts couple stopped on the side of the road and gave me a lift home. Bike is fine, maybe a tiny scratch or two but nothing to weep over. Got a little cut on my arm but overall im alright, just another day I guess. Taking it down to the LBS tomorrow and getting it fixed up, if all goes well I might get back on the road tomorrow and try again.
