A really aesthetic line which catches your eye when you wander through this area. It has some nice slopers that might give you a bit of a pump and it ends with a powerful move to reach high enough for the good hold. Must try in this area!
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.
