This is just me but if you "lose" a bail of barley. Itll all work the same. Another is milk, If you leave a new, unopened carton of milk in the sun for a week and it "accidently spills while your taking a drink" in the woods the hogs will comma runnin. Hog feed in a barrel of water for a week gets em a little drunk sometimes too. I have a great story about that Ill tell one day.
Public, unfortunately. But if I'm not hunting, then it's not baiting, right? In fact, I think technically, you just can't shoot them within 400 yards of the baited area.
