Hi Valis,
Thanks for the response, mate - hmmm, maybe Scotsprawl would be right up your street? It covers Edinburgh and Glasgow, and reasonably close to the Scottish Fringe Toxic Zone and the Scottish Irradiated Zone (for the refugee angle). Plenty of wilds in the Highlands, plus druids, for the wilderness angle. PM if interested?
Out of curiosity, where in the UK are you? I'm on the Surrey/Hampshire border.
Cheers
Sid
