Leaf peeping

As the fall colors deepen, so do the number of people who seek them. These autumnal enthusiasts are called "leaf peepers," and they can make a vacation out of viewing and photographing the fall foliage.

Of course, what better way to view fall's leaves than in a protected park, preserve or forest? Protected areas — such as Acadia National Park in Maine, Denali National Park in Alaska, and the Appalachian National Scenic Trail — provide the perfect setting for a colorful excursion.
