These hogs are smart.I just started hunting on 110 acres on Texoma that has 2 traps about 200 yards from each other.Left them open and fed corn in both,one has been cleaned out and the other has been cleaned out up to the doorway.Now here is the funny thing.Last year they set the North trap and caught 19 hogs (its a corral type) they killed 6 hogs and let the rest go.The hogs will go in the south trap but not the north trap,Letting hogs go appears to train the others to stay out of that trap. Are we educating our hogs by trapping them and turning them loose. Year 2020 hogs will be really smart.I still have notseen a hog on the place lots of track,lots of little bitty tracks. The wheat is about ready to plant and then they will have a ball. Chuck
