The Woodland Park Zoo in Seattle last year hosted a safety demonstration called the Bear Affair and Big Howl for Wolves:

This annual event features a campground set up in our bear exhibit in the zoo’s Northern Trail. Bears are released into the campground to demonstrate the results of poorly planned campsites, plus a demonstration on how to create a bear-safe campsite and promote safe interactions between humans and bears in the wild. Plus learn about another native predator, gray wolves!

First clue that you might be in danger? You just pitched a tent inside the bear exhibit at a zoo.
