I thought I’d try bacon grease a couple years ago. Had the wife save it for me in a quart jar in the fridge. Come mid November I used some down in a dirt hole and under a hay set. Two nights in a row I had a bear hooked up. Fortunately, the both pulled out. But I held them long enough to get the mother of all catch circles! I still like the idea, but I’d defer to later into January before I’d try it again.
I did catch a coyote in a bacon greased dirt hole before I pulled those sets. Interestingly, those set locations got dug out with holes like I’ve never seen before.
