Cool when I got out the door, but heating up fast. Seems like a lot of the back-to-school traffic has settled down after the first few weeks, and Friday traffic is especially light (and therefore nice).

My two cents on the tire rotating: I do it when I have extra time (e.g., fixed the flat on the road with a spare tube and had time to swap/change both tires at home), and don't when I'm rushed. When they never get swapped, the front lasts me about 3 rear tires. Still, it's nice to have extra rubber on the front. Even though the tread doesn't do much, the extra thickness seems to keep the tire from getting pierced or sliced, and rear flats are easier to handle than front. Ya ever have a front flat flying down a nice hill and you're riding the metal rim before you can stop? Not fun.
