As far as I know this was the first public, free girls meet arranged in Fontainebleau. There were only a small group of us, about 12 in total throughout the day, but this didn't reduce the high jinx and camaraderie. We were blessed with great weather, some of the best circuit problems in the forest, and made some great new friends.
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.
