I read that the design of Central Park's curving spaces was a Romantic counter to the geometry of Enlightenment-era gardens. I heard this design was influenced by landscape painting, where its foreground, middleground, and background constantly shift as you walk the paths. I find new pockets and features every time I'm there. One of my favorite spots is with the Central Park Dance Skaters, a group that roller skates in circles all day to vintage electro funk. These characters generously lend you the feeling of being in your own 1980's New York film.
An awesome, and sometimes free, ferry that links Manhattan at the Financial District to Ikea in Brooklyn via Red Hook. Very great views of the city and if you end up having to pay it's redeemable for a monetary discount towards an Ikea purchase. I think of it as a treat and an investment.
