Yep you are right. Always need to put time in the woods. Live in town and of course never killed any from my easy chair. I had just seen a couple of youtubes videos were they were using the Pig Oil product and had good results. Likely they were trying to sell it though.
It did appear that it might be good to try and use in a some of our catch pens though corn is cheaper. We just can not use corn during deer season. If Pig Oil does not attract deer we should be okay to use that, though.
It didn't work for me. I put it on two trees within my bait station. They rubbed their normal trees. It was a waste. I told them that. They sent me more......free. It didn't work any better.

I never used the pig oil but some of this mixed in some corn and you can not keep pigs off it.
I carry a gallon ziploc bag in with me with corn and this stuff mixed up and put it out where I want the pigs to stop for a shot.
