Biked to work - no problems this time. After Monday's pains, including some jerk who was blowing his horn at me for no apparent reason and a flat tire, today's ride was a breeze. I put in a thorn resistant tube in the back tire (where I got the flat), and realized that the cable guide under the cranks was broken. Yay -- yet another thing to fix. At least it appears to be holding on for the short term.
