I rode to work today for the first time since moving to Tampa. My truck's got a ruptured fuel tank, and I can't afford to fix it 'til next week. For being on a hardtail mountain bike with knobby tires and a frame 4" too small, it was a pretty nice morning. Mid-70's, low humidity, light traffic...and it only took me about 5 minutes longer than driving. I might just keep doing this.
