Some days, traffic is a beast. Autumn colors, majestic bison and Colorado’s charm bring people out to Rocky Mountain Arsenal National Wildlife Refuge, a short trip from Denver.

One of 568 national wildlife refuges across the country, we’re reminded just how much we all need space to roam. Photo by Ian Shive, U.S. Fish and Wildlife Service.
