Okay, I've had a few recently. Had a sew-up flat a few weeks ago, couldn't get Stan's to work. Been saving ujp tires to send to Tire Alert so it was time.

Earlier this week I rode a clincher bike to work. On the way home I notice a liberated crank arm on the MM Bikeway. A hundred yards later I found the stricken bike, a Limebike rental. Whoever was on it at time just left it and didn't bother going back to find the crank arm. So I went back, picked up it, dropped it by the bike. Then my rear tire went flat. Here I was, trying to do the right thing and that's the thanks I get. It was a tiny curved thorn of metal, I think, as from the claw of a nano-sized robo-mouse. Swapped out the tube, will patch it when I get a free minute, probably next year some time.
