Climbed up right where the first projection comes out of the wall (away from the edge) and went straight up. First climb, bailed for fear of a massive swing and wound up swinging anyways. Second climb, much better, but being fat (& outta shape) tough to trust my grips that require pulling myself up. Last challenge was the very top through the leanbacks.
Rating Safety as PG13, based on taking the far left and swinging into the projection which looks like would cause some severe pain crashing into it with a hip.
