No flats for almost a year, and last week two (one in the front from a thorn and one in the back from glass) at the same time. On my mountain bike. I had to patch the back one roadside oldschool, the front leak was slow enough to go home first.

Edit: On the extra heavy rim-tire combo I used to have on my freeride bike, I almost needed a crowbar to get the bead off the tire. Whenever I rode that thing I didn't bother with any flat repair things since there seemed to be no point in attempting a roadside fix.

I mostly got away with it too. The only flat over 12,000 km was from a broken valve stem... during a snowstorm, which made walking the 10km home almost as fast anyways.
