[MENTION=168558]Drillium Dude[/MENTION], I have made that mistake several times lately but not had to pay for it. That is, I didn't get a flat those days. And I rarely ride far from civilization. I did on my century ride on the 12th, and I was ready for a two flats. I had two tubes but couldn't find a patch kit. I didn't get any flats, but my rear dérailleur failed at Mile 35, so I rode 61 miles with three gears (from my front dérailleur), none of them low.
