Pratt has an amazing sculpture park open for everyone to see. 

Sculpture by Tom Otterness at the 8th Avenue subway station at 14th street 

Going for a stroll on Atlantic Beach is a fall Sunday must. I rarely go to the New York beaches in summer because of the crowds, but standing on an empty, windy beach is a total mind soother. Make sure to take a peek at the Miami-colored Catalina Beach Club. Beaches close mid-September.

My favorite place on Bedford Avenue, this bookstore has both new and used titles. If you're patient and look close enough, you can usually find a book that's worth more than they're asking. Not to mention their stellar selection of magazine titles. Good for design, art, photography, sociology, fiction, and everything in between.

Lunch there before a visit at the MET with a walk in Central Park
