I pinch flatted yesterday on a long, chunky-gravel road. I'd dropped the pressure a little to deal with sections of fresh, deep gravel, but apparently I went a little too far, or I wasn't light enough on my feet. Both my buddies had tubeless and they got to watch and crack wise while I changed out the tube.
(The ride was still a blast. I had a great time in the forest. I think I might buy some 650's with a 2.1" tire for rides that will be all gravel, no tarmac.)
Our view from the lunch wagon: The Pacific Ocean is just beyond that last ridge.
