Are you located in AK or WA? In Washington State, you may salvage deer and elk (except no deer salvage in a few southwest Washington counties due to concerns regarding the threatened northern subpopulation of Columbia whitetailed deer). See: https://wdfw.wa.gov/licensing/game_salvaging/And heck no, not gross at all. I have eaten more than a couple of road-killed deer, and they can be just as good as a hunted deer. Picked up a fat whitetailed doe last winter, and she was some fantastic eating. As for bait piles, you could probably use a pretty banged-up deer!
