I'll second that. Hybrid cottonwoods at least, the plains cottonwoods are great, in my opinion.
Also second the Spruce, I like the trees but don't like working with them.
Dead Siberian Elms, horrible and dangerous in every way.
Silver Maples, same...
We have an abundance of Triacanthos var. Inermis, they're some of my favorites in the area, very tough and beautiful trees.
