I'm feeling beat this morning. I woke up late to find a flat tire so I rolled out my trusty GMC Denali, strapped the lights and pump on it, felt up the tires and figured about 30 psi - enough for 10 miles to work - and rolled out. By then I was runing late, and dressed for rolling slow, and with no speedometer on that bike I maybe pushed a bit too hard. Made it on time though.
