In reply to Sam Beaton:
Great post.
I think mine would have to be Stanage Popular. Although it's obviously a brilliant crag, I should hate it for being so busy, tiresomely mainstream, polished and worn and sanitised; in other words, popular. I normally go by the rule of thumb that if other people like it, it's bound to be utter crap.
I can't think of any particularly amazing days I've had leading routes there, but I have really vivid memories of going up on my own when things have been really OK in my life, and when things have been not so good. Despite being the busiest crag in the country, I associate the place with peace and self-reflection as I potter up and down the crag in a world of my own.
And of course Stoney has a perverse charm. After really boring yet stressful, unrewarding days working in the civil service I'd spend a summer's evening completely absorbed in some terrifying scrambling/multi-pitch/abseiling adventure on terrible polished choss, all within the fumes and noise of a busy A-road. Daft, but fun.
