Caveat: Having never seen those dumpsters, I have the nagging feeling that I could well be outsmarted by the bears.
There’s another factor though: The bear will keep trying over and over if it smells something in there, for hours if it feels like it. Tourists, meanwhile, might not even try again if they can’t get it open right away.
My grandma thought that there was a very intelligent mouse living in her hallway once. It would occasionally do a little squeak at her but never be found. She was a bit cross when she learned the truth about her mousy friend.
I also know of an older couple that was convinced the noise came from an earwig queen(!?!) that lived inside their living room table. Much more concerning story, both if true or false.
Make America Sick Again. But not, like siiick, dude!
