There is/ was a farmer here in Southern Illinois that resorted to painting C-O-W on the side of his black angus herd and keeping them in a feedlot during gun season. I always kept our horses up during gun season too, since the ground across the road was leased to unknowns.
There have been documented instances, according to IDNR, of goats, sheep, and calves being logged in at deer check staions - back when Illinois still had them. Many, many hunters from Chicago and other urban areas come here & assume anything in the woods with fur & hooves has to be bambi. IDNR actually resorted to printing a picture of a deer on the derr permits themselves to show what one looked like. Sad, stupid, uncalled for.
