On Sept 13, 2013 we were on Skyline Drive in Shenandoah National Park when there was an apparent emergency. We were stopped twice for emergency vehicles. The second time was near the middle entrance to the park which has a wider area for a helicopter to land. It appeared that a patient or patients had been transported by ambulance from the original accident site to the helicopter landing site. I took pictures which revealed that the helicopter was Pegasus. Check out Pegasus on their Facebook page. Some of the pics were taken on my phone and some were taken on my camera.
