I think that's a very good comment. Many of these historic trees are in fact braced, trussed and filled in ways that preserve them and keep them alive. They're extraordinary measures, if you will, but people care about and want to have these trees—are awed by these trees—enough that they will take these kinds of measures.
I'm just looking at Ms. Kusie over there. There's a tree in Calgary, I think—the “Stampede” elm—right in the middle of a parking lot.
