Today was one of those commutes where things kept slowing me down. Caught a bunch of red lights, and then got stuck behind a tractor going slower than my usual speed for about a mile. Then, I got stuck behind a dump truck downtown that was extremely slow starting from every stop sign and light. Still made decent time, however, because I was riding my fast bike. We are having some of the hottest weather of the summer this week and it's also very humid, so going a little slower isn't such a bad thing.
