While we're revived...
I was riding my MTB in a wooded area along the Potomac River in northern VA. It was a very cold winter day, and I was perspiring when I emerged from the woods onto a roadway maybe 4 miles from home. Stopping to catch my breath and snack briefly, a flattening rear tire showed itself.
While I normally have little trouble changing a tube, or even patching, and being on my way, this day was different. I began to lose feeling in my fingers and started to chill down. The more I fumbled, the worse it became. I was unable to even manipulate tire levers. So, I bailed...calling my wife to come and get me with the car. Even she commented that this was an unheard-of occurrence - my calling for a ride. Stranded? Yes. Fortunately, I had a easy escape available.
