I said to myself last night that I was going to ride my bike to work today," no matter what". Well, I got a flat before I got out of the driveway. Fixed it, and got a slow leak on the way. Managed to make it to work ( 13 mi one-way) before the pressure got too low to ride. Got a nearby bike shop to fix the leak in order to save my only CO2. The ride home was smooth and fast. I feel good. And, I realized that flats are a quality problem- they mean I'm on my bike. Think I'll do it again tomorrow!
