Thanks for the tips and ideas @nolnoclaup. The simulations would be worth a try although we often get snowed in for a week or more in the winter and can't get off the mountain so have to go native on those occasions.

Visual obscurity is something that we are quite strong on. We are about a third of a mile from the road and have now planted about 10,000 trees between the house and the road. As they grow up we are disappearing from sight on the road.

I am trying to build up some surpluses - particularly in medical supplies and tools - for trading.
