Congratulations on the 40-miler!
My ride today featured my first flat in which I had to deal with presta valves. It was also the first time I had used my frame pump. Let's just say things didn't go very smoothly. 50 minutes later I was back on the road, although soaked with sweat. Good thing I had a cologne tester at the office - I'm sure I smell like a sasquatch rolling in a pig sty. Geez, I hope I don't get a flat on the way back...
