When I visited Mund's Park just outside Flagstaff, AZ, last Christmas, I met a resident that heated his house with wood.
His house was next to the National Forest with a gate for his truck and trailer.
Permit for wood cutting was $10 per cord.
Wednesday was "wood cutting" day every week. He and his neighbor would go out, cut some trees, and process them back at his house.
He had an assembly-line operation in the back yard with 10 cords in reserve.
He was in his 80's.
I was impressed.
