Super horizontal fun, starting further into the cave than you imagine. Keep those feet on and get creative. From the lip, traverse a little to the left for a fun mantle.
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.
