OK so the lone rental house on our street has a huge mature cottonwood tree in the front yard that is snowing in our yard and others. I'm getting pretty tired of it. For the benefit of myself and all my neighbors I am thinking of trying to kill it in some way. Anyone have any ideas? Its almost to the point that I wouldnt mind spending the $1000 or so it would cost to remove the tree myself, but I'm looking at all options, including 2:00am incursions into enemy territory to dump gasoline on a tree.
