I crashed in the park earlier today (err...yesterday). Broken nose and some road rash, but no concussion. However I can't remember any of it. I remember riding, and then I remember sitting on the ground with a napkin under my nose. So...

Did anyone witness a crash in Prospect Park today? Specifically a guy in an orange jersey riding a green track bike around 7:30-8pm? What caused it?

(BTW, this has also been posted in the road forum).
