I was helping out with this event over Easter in Fontainebleau. These are important issues especially in popular climbing areas like Fontainebleau. I managed to get some climbing in too and sent Satan I Helvete bas 8B+, Atomic Playboy 8A+ and one of the hardest problems I’ve climbed in Font, though only graded 8A, called Londinium!
