Photo Gallery: Celebrating the National Parks Service Centennial on the Appalachian Trail

I haven't hiked the Appalachian Trail since 2010, when I did a few legs of it in the Great Smoky Mountains and the Delaware Water Gap.

But I couldn't pick a better place to trek on the 100th anniversary of the National Parks Service than the AT, which snakes through Shenandoah National Park. The kids (and I) enjoyed a break from meetings in sweltering Washington, D.C., for a couple of days.
