Brazen bear walks off with 2 dumpsters of food http://www.cbc.ca/news/world/story/2013/08/02/bear-steals-restaurant-dumpster.html
Think the OP title should be "People in Colorado Catching On". There are a number of places in CA bear country that require bear-proof dumpsters just to prevent this sort of thing. Once they get used to coming down to the back of your restaurant, its really hard to keep them out of human habitation. This generally is a death sentence for the poor bear in the end.
New of course, but that stuff we had at school which was all slippy on one side. They don't get the soft stuff until they become SPs.
