with that feeder unfenced, if you have a bunch of hogs hitting that feeder on a regular basis that could be decreasing your deer sightings. I hunted north of Cisco for one season 3 years ago and was the only hunter of 6 that had a legitimate feeder pen. I saw more deer at that stand than all the other guys by a measure of close to 2 to 1. It can make a big difference.

Someone strums a mandolin, soft gulf breezes blow
