Vallée Chaude is a beautiful, quiet and spread out area with some great lines. Nice place to visit on a crowded weekend day . The crux of this low ball is the far move up. The foot and heel placement is key.
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.
