Hope them PETA bozos don't read this. They got on the Prez for killing a fly, they would really go into a spin for running over opossums with a bush hog. You need to paint 5 little opossum track on your cutter to signify your kills.
The PETA folks are there as an advocate for the "ethical" treatment of animals. While a bit over the top at times I see no harm in being kind to our fellow creatures on this planet. I like a nice juicy steak as much as the next carnivore/omnivore but take no pleasure in the needless torture/slaughter of any animal.
