The results of tonight's ride...
But, thanks to advice picked up here, I knew that I could limp home by wrapping the tube in a wrapper. It lasted just long enough got get home on two wheels.
I guess it's time for a new tire (this one only had about 20 miles on it). I even checked the pressure before leaving tonight (I usually keep them at about 100lbs of pressure)
Any recommendations on a pump as I had a hard time getting clyde supporting air pressure in the tube (presta valve).
