how did I not know about this. I'm struggling on selection. Part of me wants the firs or spruces to line the front my lot since the ash are dropping like flies and they make great sound barriers. The other part me wants to line a portion of my lot with that maple mix for the fall colors (though I despise their shallow root systems). Many thanks for pointing this out. I've just forwarded to everyone I know. Absolutely win/win situation for both the donor and the organization.
