Don't sweat it. I may have jinxed myself because I stated to someone this summer that I never get flats. These are the first flats I have had in 3 years. I am running 700x25 and the tire is new as of last fall. I usally run 100 - 105 psi in my tires. It's weird because I have eyed the rim, rolled it over a flat surface without the tire on it and still can't pin point anything.
