If you go somewhere near people and there is pine growing, what you tend to find is small twisty wood, everything else has been long cut for lumber. All the houses one generation ago where built by the guys that live in them and made from wood they cut.
I spent last summer hauling cutting sticks and we had to cover a lot of ground to find them as they are fairly rare now. I have not even seen a piece of pine more than 12" locally in a long time, which is fine with me because that is enough to carry around. Nice wood to cut, exceptionally soft, and splits decent when straight, burns horribly though, just flash burns when seasoned.
Most wood people burn is also basically lot selection, management consists of removing the dead and damaged trees unless you are clear cutting for building, so a lot of wood piles are highly concentrated with really gnarly wood, hell to split, most don't, just use a wide face stove and well seasoned wood.
