don't complain, that's a cheap lesson. They do have some benefits, I keep one (a single glueless patch) in my wallet as a sort of absolute last ditch flat repair. I don't always have a tube, or a real patch kit, and I sometimes go for impromptu rides, so i figure if I'm 20 miles out, my cell phone is out of batteries, and my tire flats, I unscrew the wheel with my teeth, pry off the tire, patch the tube, then inflate it with the sheer force of my breath.

Ok, in retrospect, I'm gonna take that out of my wallet
