That's why I've yet to get a chance to learn how to change tube and fix flat.

I really don't understand why others get so many flats. Do people abuse bikes? Or is there a weightless God? Beside being careful where to ride (avoid potholes and bumpy surface, etc., though not totally avoidable), the only thing I could think of is maybe avoiding weight/load helps? I rarely carry heavy things, don't carry any locks if I know I'm not going to need them--heck, not even a helmet

. FYI my tires are Kenda K-192 w/Kshield, 700x35c. Maybe that's a good quality tire?
Flats are funny things. Riding tubulars I've gone over 4,000 miles without a flat, and had more than one unrelated flat within 30 miles. Once a small group of us went through our entire pooled stock of spares within 12 miles (don't ride PA32 north of Frenchtown).
