So your saying I shouldn't dress in black and crawl through the neighbors yard?
Actually I have quite a few county & state parks within easy driving distance. There are quite a few white mulberry, Morus alba, trees around. Those are the trees originally used in China to raise domesticated silkworms. There is also a more native mulberry, the red mulberry, Morus rubra, that is common in the southeastern US. Supposedly those will work as well. I'd rather find a white mulberry if I can, because, well, a few Milena of Chinese silk farming can't be wrong.
