Two flats in one ride! First the front, then about 20 miles later, the back. Fortunately, I had two spare tubes and plenty of CO2 with me. And fortunately, I didn't get another flat, because I hate patching tubes! I'm wondering if it was just bad luck, or if I need to replace my tires. They (Continental ultra 2000) only have 1,100 miles on them. Shouldn't I get more mileage than that?

p.s. It was still a BEAUTIFUL day here in Phoenix, where the early morning temperatures were below 80 for the first time in months. Fall is coming!
