Last time I paid for wood was 30 years ago. Three of us heated our houses exclusively with wood and would annually go in together and buy a fully loaded 18-wheeler log truck load. That was about ten full cords and we paid $300 total. So I got ~ 3 1/3 cords for $100 or less than $30/cord. Heated the entire house for $100 a year. Those were the days. My wife grew tired of the smell, debris, and bugs that came with the wood, so I took the stove out and turned on the gas furnace.
I've never paid for wood since then and can get all I need (and more) from land that is being cleared for construction or the occasional tree that gets blown down. I live in an area dominated by hardwood forest and have collected oak, hickory, maple, and other species. There's wood products company here in town that gives away scrap wood (mostly oak) during the summer. I have more than enough nicely seasoned wood in the basement.
I feel bad for those in the mid-west or urban areas that have to buy wood.
