Keep the deer feeders going! Hogs also I found make a big circle miles if they were there they will be back. it may be a while. I keep 6 feeders going year round and i dig a deep hole and sink a 5 gallon bucket filled with sour gain with Apple cider they drink and eat it down as far as they can. and I fill it back once a week. I also found that if you go out hour or two before daylight I can here them grunt or squeal right before they go out feeding! kind a like coyotes howl before dark. I also sometimes smell them. I also hunt arrowheads and walk a lot but only 5-6 times in two years have I walked up on them by chance.

if none of this helps try eating some slop before going out and think like a hog! BE THE HOG!
