I've never been able to find any discernable pattern for hogs other than boars who roam over a particular range, but they patrol it pretty randomly and will move quickly if threatened or searching for food.
As for bait, I use a 2' long piece of 4" PVC capped on one end with a screw-in cap on the other. I drill several holes in it, fill it with corn and attach it to a tree or post. The hogs root it around and it slowly spills corn. It allows for better placement than stand feeders. The one I'm using now has too many holes so I have to go fill it every couple of days.
