Not yet, but if the heat doesn't get me, surely the cold will, right? Of course, I rode in that kind of heat yesterday afternoon and killled over 70 oz. of water in under 2 hours.

Friday afternoon, I left the office just at the tail of the rain, but because it had been heavy and I thought it might have cooled things off, and mostly because I wanted the extra conspicuity, I decided to try out my heretofore unused Showers Pass jacket. I don't think I'll wear a rain jacket in the summer ever again -- I was just as wet as if I'd been riding in constant rain, and I probably would have been drier had I left the jacket in the pannier, because the breeze would have dried me off as I rode.

About 4 miles from home, while riding on the MUP, I got a flat (first of the year?). I pumped the tire up, rode another 2 minutes, and flat again (and thanks to the lady cyclist who stopped to make sure I had everything I needed!) So, sure, I could have changed it on the side of trail, but I wimped out, limped it to the next good spot by pumping it up two more times, and had my wife come pick me up. It might have been faster to fix it, honestly, but I didn't feel like sitting around in the post rain muck messing with it. Oh, it might be worth mentioning that it was my front tire (which makes me an even bigger wimp).

Not strictly a commuting issue, but I used this as an excuse to put on some 23c tires that my daughter's boyfriend lent me to try out for my century, and once mounted I took them out for a 'fun' ride yesterday afternoon. They might be faster than my 37c tires, but I KNOW they're harsher -- my blinky popped out of its housing 3 times in 30 miles. I promptly switched back to my 37s for commuting duty (and then took metro this morning because I need to be at a swim meet early this evening to time-- Back on the bike tomorrow, though!)

I guess the commuting upshot here is I'm impressed with you guys who commute on skinny tires all the time -- maybe I just need to HTFU but it seems like I'd have stuff shaking loose all the time if I rode on skinny tires. Anyone have a sense of whether I'd see a noticeable increase in comfort if I moved up to 27c? I want every reasonable advantage on my century, but I'd like to have all my teeth at the end.
