No. I looked it up = a short-lived amusement park in Baychester, Bronx.
I did the same thing with a friend's boat. We had two outboards on the back - his 2 horse Evinrude and my dad's 3.3 horse Evinrude twin. Across the Sound to Lloyd's Neck, anchored, climbed up the big sand cliff called Sandiggers and slid down. The cliffs are still there. My friend unfortunately is not. I took a picture from Greenwich Point with my Nikon P900 900 mm lens. If I can find it, I'll post it. The Sound is 6 miles across from Stamford, quite a bit closer from Rye and very narrow going into the East River.
