Been there once - ended up lurking around the boulders at the base of the main crag while some local lads were having fun with their air-rifle down by the water. Nice place for a visit, but I didn't really get into the climbing there. I guess if you're local you'd be forced to get a lot more out of it?
The neds pushed off and I bouldered a bit with a guy called Craig - nice guy, med student, very very strong but with one of the worst memories for sequences I've ever seen. He managed to link some traverse with me reminding him what he'd just done while working it.
A year or so later I saw him at Malham, where he onsighted one of the 7cs right of Obsession despite wet holds and immense rope drag due to clipping bolts on an adjacent route. I suspect that the only thing that stopped him falling off was the certain knowledge that he'd never remember what he's done to get to that point.
