I had a premonition last weekend, and checked to make sure my spare tubes were still good. I had some wear through at the corners of where I folded them once. The very next day a sliver sized piece of glass worked it's way through my rear tire. I just about had to destroy the tire getting the sliver out. ugh. At least it wasn't cold or raining and I noticed it right next to some nice benches over looking the river. So at least I had a pleasant enviroment for the "layover".
Plus the Army ROTC unit ran buy and at least a dozen of those guys asked If I needed any help. I always enjoy observing kindness.
My record for flatty flats is four in one day, including a double (two pieces of glass in unison) on the front tire. I so wish Ohio would pass a bottle return law.
