Here in Wyoming we are regulated by the G&F so our options are limited. We can use a bucket/barrel up to 50 gal, has to be attached to tree, cannot be closer than 200 yards from water, roads, trails and 1/2 mile or more from campgrounds/cabins. We have to register a bait with the G&F and are only allowed two, with no one elses bait (including yours)within the same square mile.
Baits you can't use: "big game animals, small game animals, game birds, game fish, protected animals, protected birds, or parts thereof."

But some guys just dump it on the ground.

I'm going to use oats and mollassis this year along with spreading grease on the ground around the barrel(s). Years past I've had success with donuts and hanging rotting chicken/turkey in small mesh bag in tree above bears reach.
