I'll look that site up later. I like hot tubs. I think my wife would give me some strange looks if I showed up with snorkelling gear and we were not in a tropical area.
Figured I'd update my winter's usage so far. With the way our weather has been going, I'll probably use 3-3.5 cords of wood this year. I've been using and not refilling the patio stack. My plan is to not have to move any of that stack, to the stacks for future seasons. If I have to, I'll do it though.
