Augh, same thing happened to me once. I have several people to call, but just like the OP in the other thread, I didn't have my cell phone and I don't know people's #'s. 7 mile hike for me. Unlike that guy, I sacrificed the tire (which was older anyway) and rode the thing with the flat on downhills (very slowly) or pushed it. No way I'm carrying a bike for 7 miles!
I created a contact list which I keep in my seatbag now. It's always on the bike, so I always have it.
