Open Gates, and a bit of naughty

To do this weekend, details courtesy of New York Magazine:

Stroll or cycle alongside the largest artwork since the Sphinx.
The brainchild of eccentric duo Christo and Jeanne-Claude, The Gates is literally 7,500 gates hung with billowing fabric, standing 16 feet tall and spaced throughout 23 miles of Central Park pathways. The exhibit's opening coincides with Valentine's weekend and tour groups are eager to get in on the act. Official park walking tours offer their take on the project's 26-year history, prior Christos endeavors, details on the Central Park itself and a few surprisingly salacious anecdotes (who was arrested at the zoo for pinching a woman's behind?). For the more ambitious, there's a four-hour, 10-mile bike tour; for the more romantic, here's a handy map for a do-it-yourself, after-dinner stroll.
