I had one pinch flat last year (about 2000 miles on my road bike) when I hit a stick on a rapid descent on my driveway (30+ mph). My summer was flat-free except for the one pinch flat. This fall & winter I've picked up wire, and a couple of pieces of glass.

I know I've had the occasional snake-bite flats in the past, but hadn't really realized the cause.

I tend to try to avoid hitting big bumpy stuff, and slow down for things like rough RR crossings. But, I have also hit some road debris on the shoulders without flats.

I did try to put in about 100 PSI in my tires a couple of times this year, but didn't really like the extra bumpy feeling (perhaps a sign I should be riding bigger tires, but I still like my small tires).

Not me, but I've seen clips of wicked single-bike corner crashes in races that I don't think should have happened. It appears as if the bikes just slide out from under the riders. I do wonder if some riders are using too high of pressure.
