Evening commute...
First time in months that I've been drenched - like "I jumped in the pool with all my clothes on" drenched. I always ride at an easy pace when I commute, so I didn't have to brake hard. Mt. Vernon Trail wasn't totally emptied out by the rain - there were still some dedicated runners out there.
At E. Glebe and Potomac Ave, there was cyclist lying on the ground, in the middle of the intersection, with a bike lying nearby. He (I think it was a he) appeared to be unconscious, with a blanket over him, but was surrounded by concerned citizens, one of whom was on a mobile phone, presumably calling for help. Traffic in the direction of that intersection from Potomac Yards was totally blocked, because nobody wanted to risk moving the injured cyclist, though any of those cars could have just turned around and taken any number of routes through Potomac Yards. I did hear some sirens as I rode away from the intersection.
