Flags, I agree Bacon grease and such works better, butt also can illegal
as in some places that allow baiting,
they don't don;t all use of any meat o r meat by products
lots of rules now on baiting
and many even require ALL bait and bait residue be removed after a certain point,
so grease gets tricky there too, as it again soaks into things

so, anyone using bait, make sure you check laws and what you can use and NOT use really good, devil is in the details and don;t want to get a fine, or have a bear you get taken off you due to a small error on not knowing fine print like so to speak!
