Hi Andy, working tomorrow so can't make it but cha1n (ross) on here is fairly local to Huntsham and may be around - might be worth dropping him a message. there's space just down from the coach turning circle on the opposite side of the road for a few cars - I've never had trouble parking. like AJM said, esoteric bouldering (think you might need to use the wayback machine now) will give you the gen, or boulder britain will get you round most except the bivi buttress stuff, which is on AJM's blog.
