This is a little harder the shorter you are, but its actually loads of fun. The holds are ok when you get to them, so commit to the swings and hang on :-)
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.
