I've got an ash tree next to my barn that has to come down but before we do there are a couple of black locus trees that need to be removed to make room to drop the ash tree. I've cut and burned a lot of black locus since moving here many years ago and know its great fire wood. Problem is the brush - its full of thorns and is miserable stuff to handle, even with gloves. Fortunately locus trees are no where as brushy as ash trees and they don't blow up when hitting the ground. I dropped the tree into a corn field so I have to make sure its cleaned up pretty well so the thorns don't go into tractor tires (they can). I've got the bigger one on the ground so it gives me something to do for a few days. There is still a smaller one to get down but of coarse it has to be leaning the wrong way then I can get to the ash tree. Probably all the trees will make a full year of fire wood for me on top of about 2 years of wood already cut from previous ash trees. I've got probably 10 years worth of fire wood in standing ash trees and at least some will rot before I ever get to them. Already see wood peckers working on some of them. Its too bad what has happened to ash trees around much of the country.
