I think jrbsr nailed it. We had the same thing happen with a couple of awesome Bucks right after the corn was cut and the beans where harvested in a friend of mines area. Once the food and cover were taken away they seemed to move on into the heavier cover areas. I am curious to see if some Bucks I'm getting on my cams stay in the area where I'm at because there are no crops within several miles of where I'm seeing them at present.
