‘Golden Roc’ might be the weirdest boulder I’ve ever climbed. I’ve never found myself with my head between my knees and my hands just next to them. But well, it worked!
Rain sucks, but broken holds suck even more. Remember, never climb on wet rock in Fontainebleau.
The sandstone becomes brittle, and pulling on it will ruin classic problems. Drying it doesn't help, because it's still wet and weak inside.
All you can do is wait for better conditions.
