Big boys just don't hit food plots that often. Mostly they will hang back out near the hard woods. Look for them there. They will also bed in the meanist thickest mess you can find. They have alot of factors to add in before you get a good mount. Stay off the heavy trails. Find the ones that show very little use and within 100-200yds of feeding areas. Look for scrapes rubs use your nose smell the air and hunt him down. Remember to much pressure and he'll disappear. Find that spot learn it remember every branch and stump. Go back to that spot occasionally not to much and wait him out.
