Thanks guys. We do have some huge locusts around here - some as much as 24" in diameter. In fact one of our neighboring towns is called Locust Valley because it is heavily populated with the stuff. I've already told my wife that if we move from Long Island, I'm taking some saplings with us.
Anyway, I chopped up much of my locust and set it in my garage to dry. I will be using it for risers. Unfortunately I didn't have any pieces straight enough for a bow.
