Hang a stinkbag,onion sack/leaky bucket etc. full of fish/rotten meat....whatever,so long as it smells strong.Hang it from a rope high enough that the bears can't get at it.Doesn't matter,they aren't gonna eat it anyway,this is just to get their attention from a long distance and draw them to the real bait,which is a 45 gallon plastic/steel drum full of popcorn and fryer grease.Chain the barrel solid to a tree,and cut a 6" diameter feeder hole near the bottom so they have to work for it,shake the barrel etc.,and it'll last longer.Hit up your local movie theater for a steady supply of FREE popcorn which they discard nightly.You know,that same stuff that they charge you $6/ounce for at 9pm.........it's FREE after 11,LOL. It's alot lighter than day old Tim's donuts and bears love it.Plus,once you get hit,they get the grease all over their paws and leave a scent trail back to the bait for even more bears to follow.
