I just got a flat coming to work today this morning. I've learned 2 important lessons:
Never lay your wheel skewer nut loose on grass, especially like grass as tall as you.
Put extra skewer nut inside your seat pouch.
I spent 1/2 hr looking for this stinking nut. Combing and brushing through weed grass like someone trying to run away from "Children of the Corn". Luckily there was a mechanic shop nearby that's kind enough to spare me a nut and 2 washers. Now I'm keeping my fingers crossed that it will hold strong enough to get me home.
