clo,
I'll give it a try! I notice one of the comments at your site is from someone in Buffalo. He says he's always had Black Walnuts in his yard.
I'm not sure how the temps compare, though. Buffalo gets tons of snow, but I'm not sure it gets as cold as NH. Then again, I haven't been through a NH winter. My concerns about it may be exaggerated.
