Thursday and Friday nights, the National Park Service offered a "once in a lifetime" opportunity to visit Ellis Island and the Statue of Liberty at twilight as part of National Parks Week NYC. It was the first time in history that both attractions were open at night.

In addition to tours of both parks, there were screenings of The National Parks: America's Best Idea, the new documentary by Ken Burns. The six-episode series premiers on tomorrow at 8pm on PBS and online from 9/28-10/9. More National Parks Week NYC events at Feel Free.
