wouldn't worry about that, I'm just back from Greece, the locals seemed happy enough to sit around the town squares cuffing Amstel at 5 euros a pint, so the shite they flog us in plastic cups is a bargain
just looked out my window and the sky looks like i'd imagine it'd look half hour after 'the bomb' has been dropped, hope that information helps (bit puzzled by your second line though, I suppose The Alps would provide a bit of shelter but dont think it could help us)
