A great way to escape the city...Especially amazing in Spring when the cherry blossoms are out. I love the Japanese pond, the famous NYers walk with plates for Arthur Miller or Lee Krasner and of course the green house.
After the full moon, when the tide is the lowest, you'll find a century of fossils from a gone NY, trails of washed-out rainbow colored bottles, a graffitied shipwreck buried by time. Hundreds of years of history written in the sand.
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.
Luhring Augustine did a good job of converting an old warehouse/storage facility into a blue chip commercial art gallery that stages four shows of contemporary art per year. Which means you can catch museum quality shows in an unlikely spot, away from all the Chelsea pomp, and it actually has friendly staff, instead of a cold gallerina sat behind a desk pretending to be on the phone.
