Bears live by their noises so get a lot of scent out there. Once they recognize your location as a place where there is food they will continue to visit. There is a lot of info on u-tube. I spent hours upon hours reading and looking at videos. When I finally got done it was clear to me that someone needed to put all the info in one easy place. That said I made this quick clip on Who to build a bait barrel - . Additionally, I am a huge fan of a stink bucket (its in the video). This is a easy way to greatly increase the amount of scent you are putting out there.
