I took a 45 minute train ride from midtown to see this place, what a DUMP! There are 3 sculptures, all are so bad I think a 3rd grader made them.. It is more like a dog park then a sculpture park. it's in a really gross area of town too, taxi repair shops and trash all over the place.
Save yourself the time..... If you want to see something special take a trip to Storm King Art Center, just a short drive outside of NYC.
