If it wasn't locust, it was his twin brother. Tiny little leaves, 50 ft tall, thorns on the branches. 2 1/2 feet in diameter. Tiny white flowers all over it for about 2 weeks that smelled kinda like honeysuckle.If your locust seemed "easy to cut up, like pine" then is isn't locust. Locust is harder than oak and even harder than hickory.
