I had a flat on the front the other day, I seem to flat more in the front than the back. Only thing I can figure is it's a Bontrager tube that's been on the bike for more than a week.
I @!#!#@!#@ hate Bontrager tubes.
Anyway, I second the recommendation of taking a spare tube with. I don't mess around with patching anymore, that's my one luxury in life, I guess - LOL. Spare tube, nice Park Levers and a frame pump - you'll thank me later.
