I get a 45 gallon barrel and cut a small hole in the side of it. Just enough for a bear to get a paw in. Then i make a small hole at the bottom of the barrel and run a chain through it then chain the barrel to a large tree. Make sure the lid is on tight and your good to go. I also hang some beavers up in trees, check out the best bait in my book post alot more info there.
