I took the Roosevelt Island Tram over to see The Encampment By Thom Sokoloski. It was quite fascinating. He had set up 100 Civil War Canvas Tents on the Southpoint of the island next to the old asylum. They were illuminated from within and each one told a different story about the people who had been interned in the Island Hospital between 1828 and 1955.
Unfortunately the show only runs from October 5-7 so you only have two more days to see it. It’s open to the public from 7pm- 1am and is left lit every night until 7am. If you have the chance go see it.
