Just got back from our second thermal hunt. Our timing wasn't great. We only saw four hogs. Shot two large ones. The other two we saw were running between cedar thickets. The ranchers said they just were not seeing them. None of their fields were planted. Therefore no food, no hogs. We had great luck varmint calling. Shot two coyotes at night and another during the day. Plus a large bobcat at night. We used the thermals on the night calling sessions. They worked extremely well.
