Definitely do think about all the trees I see and do pester my wife about them when we're out for a walk.
Mostly I think about every Bradford Pear I see and how much pleasure it would be to cut 'em up to little bits. Then I would get the property owners to plant real trees in their places.
For a while I would be looking around a neighborhood and exclaim at how many trees will go when EAB hits the area. That was three years ago, she got sick of it pretty quick and told me to lay off.
