No, it's quite a secretive hobby with people reluctant to give away locations, due to the amount of wankers who like to burn places, spray them or vandalize them.

Ah of course, I didn't think about that.

Just read your linked post, thanks. Definitely something to think about. I'm trying to get a bit fitter as I'm really horribly out of shape and overweight, maybe something like this will help. That or it'll finish me off, but at least I'd have fun on the way, lol. It's more motivating than a boring walk anyway!
