BurbleChaz

After my puncture I resolved to be better prepared. I bought not one, but two new inner tubes, took the old one out, replaced it with a new one, and put the spare in my CamelBak. Sorted. To demonstrate to my rescuer just how tricky tube repairs are, I put some air in the damaged tube. The pressure held. And held some more. The punture, smeared with rubber solution, had repaired overnight.

For reasons I do not fully understand, this caused amusement in certain quarters.
