Well, I'd leave the poison Ivy alone for starts. Cedar is great stuff, especially when bamboo backed. I have some boo growing on my place, I'm happy to share. Ash makes a decent bow, not sure about Texs Ash. The live oak and pine oak may do well, but I never messed with them. I'm heading through central NC late next week, toward the weekend, and I'm hauling my osage stash. I'd be willin to drop you off a piece or two if you like. Maybe even make a trade for some cedar, I will be hauling some bamboo with me also...
