I've seen carcasses dumped on our hunting property near the road. Makes me mad and wouldn't do it myself. Here in MI it is encouraged to check a deer, but not mandatory. These check stations are only set up during the two weeks of firearm season I believe. I've never checked a deer. I bought the tag, put it on the deer, I'm legal. If it were mandatory, I would check the deer, but since it's not, no harm done by not.
