55F or so, seemed warmer than that after a couple miles. Nothing too unusual although one SUV decided to slow to a crawl and block traffic when I was about 300 yards from my destination. I went around to the right and just as I was passing, the driver decided to begin to turn right without indicating (even though you can only go straight there - it's a one way street the opposite way if you turn right). I hit the brakes and the bike skidded a bit, but luckily the driver stopped the turn - I guess they either spotted me or realized the turn was not on. Pretty sure the driver was either new to driving in DC or trolling for a street parking space during rush hour... good luck.

To balance it out a bit, there was a guy dressed in black mashing pedals weaving lanes and blowing red lights about a mile before that in Georgetown. Strangely enough I overtook him pretty easily once I got my green light. He was definitely riding in too high a gear. Or maybe it was a fixie.
