A couple years ago I cut a branch of box elder and sawed it square in hopes of using it as a riser. I never used it though and I don't plan on it. It's very light in weight, it has small holes as in Ty's picture, and it has punkie rotted wood mixed in the heartwood. The pinkish color is result of the wood's defense of the fungus that plagues the tree. After seeing a dried piece in person, I think it's best used outside of the bow world.
