So I feel a little mushiness. Hmmmm We saw a spot of shade a short distance ahead and got into it. I said "We'll just pull the tube without pulling the tire and patch it." Bob, ever the enabler said "Right On." This is the Michelin Ultra HD tube. It's more like an "Inner Tire". It's NOT easy to deal with on the roadside. Anyway, we got it out, found a hole and patched it. I'm thinking we will be on the road soon as I put the tube back into the tire. What I should have been thinking was "I wonder if this nail made holes on the inside of the tube." After re-mounting the tire and inflating it I knew a little more. We dismounted the tire again, added another patch and re-mounted the tire. In the process of re-mounting the tire the bike fell off the center stand (rock). The second patch leaked. We decided to pull the wheel and put in the spare front tube that I had. The new tube worked, but by now it was getting late. By the time we got everything re-packed it was dark, but we only had 43 miles to go and 10 of it was paved. We got to Creel at about 9:30. A BIG Muchas Gracias to Tio Molcas who even though they were closed made some burritos for us so we wouldn't starve.
