Well, the weather finally cleared (although, it was still pretty chilly for a few days), so I got some outdoor rides in. The only problem is, that I was stricken with bad luck! My second day out last week, I flatted twice, and ended up riding back to the car on my rim, as I was out of tubes. Then, my third day out, I ended up hurting my lower back. This is no doubt due to my attempt to adjust my riding position to be a little lower on the bars, but I've spent the last 3 days in pain. I'm going to readjust and try to get out again today.
