Bears are teaching their young that humans = available food is aroundnearby. They We call these bears " garbage bears". They treatbreak into garbage cans, aveand often chew on any containers they can find. A bear chewed on my chainsawschainsaw's 2 stroke fuel oil can, causing oil to leak out. They've destroyed boxes of stuff with no food inside, they make a huge mess. The moment they smell coming food, they make note and wait for a time of no human activity, then raid. I've cooked outside in the forest where I live (Lake Tahoe vicinity), go inside after eating, come back out aveand have seen bears running away. It's not usualunusual for you to see them, they because they know how to hide petty good. But they getare accustomed to people not being out at night, like I am. They're confused by me. Especially if you've got night vision, and chase them away, they will keep stopping and turning to look at you, it's a weird feeling. Wolves do that too. But yes, bears around camp sites and rural homes often go for the easy food, garbage. Then teach their young. It's no Bueno.
