In reply to andrew8916:
I'm off to Coventry on the 5th September, if you can get one built there (the nearby uni looks passable, just!) then I'd greatly appreciate it. In all honesty though you're just going to get people posting roughly where they live!
I've experience of Birmingham and Bristol themselves. Red Point in Birmingham and an old church in Bristol. Both were excellent and would probably provide stiff competition in the surrounding areas.
Rokt in Brighouse has managed to carve themselves in a niche in an area surrounded by Sheffield, Leeds and Harrogate though, so it's definitely not impossible. They're very family friendly and aim to appeal to kids and parents who want to try out bouldering without any of that expensive and dangerous rope nonsense (though they do cater very well to 'proper' climbers!) and they've done very well by setting up shop in a relatively small town, directly off a major motorway in an old flour mill. I imagine the mill was relatively cheap given there's little other use for them nowadays.
Copying what they've done certainly wouldn't be a bad start. Are there any small towns close by to larger cities on the M5? Any with cheap rents or old abandoned (tall and unique) buildings?
