Well, I'm pretty sure there is a spot on my route where screws, shards of glass and miscellaneous other debris lie waiting to pounce. It's a six-foot wide, leaf-covered strip extending from one end of my route to the the other. They call it a bike lane.

The GP 4 Seasons have actually done amazingly well, to the point that I got lazy about even checking them over. When the front tire died this week it had so many tiny pieces of glass in it that it looked like it had been bejeweled. Those tires have a two-ply Vectran breaker, which Conti claims is harder than Kevlar. The T-Servs have Panaracer's PT Belt, which makes similar claims but I guess can be foiled by something with a fine point -- the Achilles heel of all fabric-based puncture protection. Nothing but a lot of heavy rubber stops that.
