Indoor climbing

Rock climbing usually involves getting from the bottom of the giant face of rock to the top of it and last time I checked London has a distinct lack of fuck off walls of rock.

Theres a shadowy night climbing scene in london, comprised largely of industrial access climbers and tree surgeons. So what if london doesn't have fuck off walls of rock. It has an almost infinite supply of very climbable walls. Many large buildings have anchors on the top edges as well so can be roped etc as well. I imagine its filthy, covered in pigeon shit and lots of jagged edges etc
I have no idea if theres a night climbing forum but i know a couple and have seen em do their thing.

This book ftw
