After my last crash, I had a bruise on my ankle in a weird place. I finally figured out it was from the impact with my pedal. Could it be that?
Glad you weren't hurt! Railroad tracks are evil.
No, it was my outer ankle. But not on the poky out bit, on the slope coming up from it. Maybe it hit one of the potholes or bumps in the road. It's just weird that I didn't bruise or scrap anything else up on my legs.
