I believe it can draw them in from a long ways off. I set up on a field where they were harvesting ripe strawberries. The pickers stepped on many and that whole field stank of Strawberries. The same night two sounders came in, merged and raided that field. That heavy mouth watering scent seemed to carry for a long ways and made it irresistible to them.

Corn always works. I typically save the last inch of my Beer for the Corn bucket, all my friends do the same. Corn soured with Beer works well for sending out a scent cone that can draw them in from a long ways off. Corn works, but first they have to find it, a strong scent makes it easier for them to find.

I've dug 18" deep holes with a post hole digger and put some offal in the bottom. Fox go ass in the air trying to dig the offal out. Why not for Hogs too, maybe just a different bait?
