Richmond, Virginia, resident Kevin Gallagher spent half of 2005, his first year out of college, traversing all 2,200 miles of the Appalachian Trail, beginning in Georgia and ending in Mount Katahdin, Maine. As if that weren't impressive enough, Gallagher, a former film student, then condensed that six-month journey by using 4,000 photo slides he'd made along the hike to create a stop-motion film. That movie, Green Tunnel, is what you're looking at above.
Assuming you don't have the time, money, or inclination to take a six-month journey yourself, just watch Gallagher's film. Not only is it soothing, it's also a reminder of just how beautiful and diverse the natural American landscape can be if you leave the city every once in awhile.
