To celebrate the autumnal equinox, we’re in Shenandoah National Park in Virginia. The park includes part of the Blue Ridge Mountains and the Shenandoah Valley, and in fall, the forests of Shenandoah offer a kaleidoscope of red, gold, orange, and brown as the leaves turn and begin to drop. Skyline Drive, a highway winding across the mountains, will be crowded for the next few weeks as visitors make the trek to take in the view as the seasons change.
