On Mac 'n' Cheese, they ripped up a road between the time that the pre-ride happened and when we rode it. It was about a mile of gravel. Everyone was standing around looking at the horribly rocky mess that was left, but I wanted lunch so I just rode over it. I always ride 32mm GK on my road bike. It wasn't pleasant, but the tires weren't damaged. I was not going back into the headwind to get to the first paved road, that probably would have taken 30 minutes. I would have been a lot happier on my 38mm tires.
