Hope I haven't jinxed myself by reading this thread - just when I think I've got myself covered for the goatheads (kevlar-lined tires, thorn-resistant tubes and slime) is about when I ride over a box of roofing nails that's been dumped into the bike lane, or the horseshoe nail from three weeks ago

None of the bus routes around here have ever made sense, but seem to be improving. More fun to ride, though (or even change that tire)!
