I still can't believe how much I keep learning about New York City's fascinating history. The Lowline is an idea that uses an abandoned trolley line to be converted into a park. Just like the Highline but underground. They say it could be the world's first underground park! I checked out a prototype they're trying out to see if its even possible. The plants looked pretty happy to me. That eventually led me to google the hell out of the old trolley system. There's something about NY's transit history that continues to fascinate me. The combo of abandoned history and futuristic ideas, yes please. Take me to another world.
