The New York Times has a good article on Bretwood Higman and Erin McKittrick of Ground Truth Trekking. They spoke at the 2009 ALDHA-West get together (as I recall). The article mostly describes their life together with their son Katmai. Good read. http://www.nytimes.com/2009/12/31/garden/31yurt.html?hpw -- Tortoise Because truth matters"
