Last night riding home in the cold (5C, approx 40F) rain I hear ssshh...ssshh...ssshh with every wheel revolution. Yep, its air escaping from a hole in the tire, making noise each time it hits the wet road. I ride a hundred feet and then it's too flat, so I walk for a few blocks until I pass a store that's empty and for lease, and has a covered alcove at the doorway.

I can't get the whole bike in the alcove out of the rain so I take off the wheel, pry the tire and pull out a section of tube. I spot the hole right away. I check the outside of the tire and pull out a 1/4 carat gem of glass. Damn wet rubber - too easy to penetrate.

I don't have a spare tube but I have a very old patchkit with glueless patches. I rummage around in the trunk bag and find some old glue too. I buff the tube and peel a glueless patch and stick it on. Absolutely no adhesion! Too old, or too cold? I don't know. I glue it and it still doesn't stick. I roll it like a dube, vigourously for a few minutes hoping the heat and pressure will bond the rubber. The corner won't stay down, but the middle seems to be stuck. I doubt it will hold but I stuff it in, pump it up, mount the wheel, and ride in the direction of Curbside Bikes, since I'm not sure Bikes on Wheels is open late. Amazingly, it holds. I buy a tube and some new patches with filthy hands, and scoot around to the alley where they have air and top it up a bit more. I'm not expecting to make it home, but I do. I figure it will probably be flat in the am, but I'm cold and tired, so I set the alarm a few minutes early so I can replace the tube before work.

I come out in the morning and check the tire. Hard as a rock. Was last night a dream? Nope - there's the new tube and patchkit from Curbside sitting right there in the trunk bag.
