In New York City, an abandoned railway track overgrown with grass, bushes and even trees, was turned into a recreational park and opened to the public in the late 2000s. It’s an interesting story which took quite a bit of perseverance from local activists. You can read about it here.
The reason I’m writing about it now is that via the magic of Google Maps’ Street View, you can actually walk the length of the whole park. It’s a charming exploration of an urban oasis, slightly elevated above the hustle and bustle of Chelsea. Click the image to have a look yourself.
