I've gone with a friend to visit one of her friends in Scotland. He lives in an ecovillage called Culdees. It is near Aberfeldy in the Highlands, and has a magnificent view of loch Tay. The 'village' is run by volunteers and is run in an ethical way, recycling as many materials as possible and being self sufficient.
