It was a balmy 48F this morning, no rain on the way in. While still in our parking lot, leaving work to go home for lunch, I discovered my Centurion's rear tire was flat. I Went back into our vending machine area & put in a new tube. It was a presta & the rim on this bike has schrader so I only pumped up to 60#. Pretty messy due to all the road grit on my bike & tire so it was great to be able to walk around the corner & wash up before riding home (if you have a flat, have it at work!). There was still lots of sanding debris on Martin WAy but South BAy Road had been swept and I could make some speed. After lunch I rode my Motobecane touring bike back & hit a few showers but there was some sun. The ride home was dry.
