We are about to break ground on a 2400 square foot subterranean Passive Annual Heat Storage house. Davis Caves will do the construction. Your advice in the past was helpful. We'll let you know how things go.
Well, I haven't been doing the primitive living as much lately, but always good to start fires (actual and metaphorically). i actually have quite a lot of fire making materials collected....if you are in need of a fire by friction kit let me know! I think it would be very cool to do a primitive float trip where one would camp along the way doing up fire and food the oldway.
