My kids could never fathom this, but when I was a kid we'd go out into the woods during the heat of the summer and cut fire wood off of the slash piles the lumber companies left behind. We paid $5/cord for the permit, then load up the Subaru, towing a utility trailer my Dad built. It would take all weekend to get a cord of wood, then we'd go back out the next weekend and do it again. Some days would go better than others, but over about 4 weekends we'd have enough fuel wood for the winter. We'd have to cut, chop and stack the wood once we got home, and we'd need to continually bring it into the house through the winter so we'd have enough dry wood to build a fire in the stove every morning, and yes, as the first up, I did that practically every morning. I thought that was pretty normal and everyone did it until I got to college. Nope, just us. We didn't get an allowance either - just expected to do it.
It was hot, dirty, and sometimes really frustrating, and yet, that is one of the things I do miss about growing up where we did.
PS - just remembered - once we were all off to college and my Dad didn't have the free labor he bought a self-feeding pellet stove. A truck would deliver bags of pellets. Dump them in the hopper, get a little fire going with some lighter fluid - instant heat, done.
