Jags said:Get a pic of these "thorns". I think I know what your talking about, and they are not true thorns (in the protection of the plant sense), they are more of a pointy growth under the bark, only to be seen when the bark falls off. This true??
If so, you got cotton wood. "Drying to the lightest wood" does not = locust. Sorry for the bad news.
Yup, not true thorns, more of a pointy growth under the bark. I'm working on getting pictures...
