Amazing weather; just right for t-shirt and shorts with minimal sweating (for me). No major incidents involving damage to me or the bike. That's about the end of the good news, though.
Oh, I shouldn't complain. The first 15 miles were basically fine, and normal. But I had a woman who was standing on the side of the Custis finish whatever she was doing and step onto the path right in front of me without even glancing first. Then I had a rider slow rather excessively and unexpectedly because there were pedestrians (admittedly, this would not have been a big deal if I hadn't let myself drift up too close because he/she was going so slowly...)
Then, I couldn't catch a break once I got into DC: they're screwing with the path between the Lincoln Memorial and the WWII Memorial, heading to the Washington Monument. No big deal, right? Just head up to Independence avenue, and ride there. Except they're doing tree work, so they had the path closed there, too. salmon for a couple hundred yards, since no cars go that way anyhow. Of course, the mall is a wreck because they're setting up for the folk life festival, so every other transit is a detour (which sometimes seem to circle into each other).
Work my way over to E Street. Trucks and cars blocking everything, everywhere (okay, slight exaggeration... but really) and I hit just about every red light. Oh, and I noticed (For the first time?) a sewer grate in the middle of the bike lane that is turned in exactly the wrong direction. Ugh!
