Well the tree I thought was Osage turned out to be mulberry. Got some. There is still Osage out there. And some thing that has been down for a while, makes tan saw dust and is hard enough to slow down my katana boy. Smells vinegarish. Elm?
Found another smaller down Osage but it is on the ground, bark is on but loosening. Black streaks I the end grain. Long straight 10" trunk. Going to be a muddy mess to remove.
