Just a note on the use of Black Locust for posts in the ground from my experience
(and old timers' lore as well): Be sure to strip off the bark before using in
contact with the soil. Otherwise locust rots as fast as any other wood (bark
beetles help this along). With the bark stripped, I've seen fence posts last for
three decades and more.
