I will also add that I hunt some properties where I can see much more than just the property that I am hunting. There are plenty of nights I can see hogs active on the neighbor properties, but that are not active on one of mine. It is nice hunting from hill and ridge tops. What is interesting is that from a hunter observation perspective, had my properties been treed or in a low area where I could not see as far, I might be apt to claim that the hogs just "weren't moving." However, from my high spots, I can see that they are moving. They just aren't coming over to where I can hunt them.
With that said, they will forget and they will be back. In the end, they can't resist a good thing.
