This is a really fun line that traverses along the lip of a low roof on big holds, and ends in a cool mantle - mind you don't bump your head!! sit start on the far right.
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.
