The DNR offers the following advice to avoid black bear encounters: Minimize attractive food around your house or campsite, including keeping garbage cans secured. Never approach a bear. Don't play dead and don't run, instead slowly back away and don't turn your back on the bear.

Therefore, it's important to keep your food -- including scented items like soaps and sunscreen and garbage -- where bears can't get at it.
