It happened again today.
I was all excited to go for a ride, since I hadn't been in a long time. Got my bike out, aired up the tires and struck out on the sidewalk. About half a mile down the road there is a trail that goes through a park. I got there and went downhill on the trail, then, there was a sharp curve with dirt covering the trail and a ditch on both sides. As soon as I saw it I knew I was hosed. If I tried to turn sharp enough to keep the trail at the speed I was going I would skid on the dirt and crash, if I tried to not turn the wheel [which I ended up doing] I would go off into the ditch and flip right over.
The brunt of the impact was borne on my left forearm near the elbow and there were various other cuts/scrapes on my left leg and various other places
My left shoulder hurts a LOT, too. I can't raise my left arm very high, but it's not dislocated or anything, so hopefully I didn't do any hardcore damage to it and it will get better within a day or two.
I think now I'll just lie and watch some TV... that's safe...
