Another bummer! I have to ask myself why I am so arrogant.
I know better. Don't cross railroad tracks except completely perpendicularly. The road was in particularly bad shape on this new route to my training class. I noticed the condition, slowed down, and started trying to unclip. Suddenly, I'm on my side. My elbow is bloodied and my back hurts. I got myself up, checked out the 'bent, put the chain back on and rode into class.
Fortunately, the blood washed out of the jersey (cold water and hand soap in the building), and everything else seems to be sore muscles. We'll see by the afternoon whether I'm asking my wife to give me a lift home. :-(
