I chose a house on a hill ten years ago when I was looking for a place to live after I inherited a bit of money. It was one of the cheapest houses in Britain at the time and probably still is. It's about 900ft above sea level in a semi-rural terraced village. The local shop/post office just closed and I feel a bit isolated.
I don't think I'll be 'going' anywhere but if things get very nasty I could do with some helpful companions. I could probably accommodate about 3 or 4 people, mabe more if things get really bad.
While I'm not too worried here about flooding or tidal surges I do worry about war and breakdown of society and Avian flu etc.
