In Anchorage, Alaska this spring, a moose walked through an automatic sliding door and into a hospital building before starting to chow down on office plants -- don't worry, they were real plants. The staff was ultimately able to direct the moose back outdoors.

Lily Grbavach, the director of education for the Alaska Wildlife Conservation Center, explained how common it is for a human to cross paths with a moose and what to do if it happens. The short answer? Don't engage.
