At lunch today I couldn't fix my rack, so my co-worker dropped off my stuff on his way home and I went to run. After my run, I got on my bike, made it about 1/2 a block when my chain came off. No big deal ... I can put a chain back on ... piece o' cake. No. The chain was stuck in-between the shaft and the frame. I am not having a very good week at all. Grrrrrrrr. At least I got a run in.
