Are you a flashmobber? One of those people who meets up in a location to do some strange action simultaneously with hundreds of other anonymous folks—and then leaves the scene as if nothing happened? Well, if you’ve missed out, no worries: Union Square is the next meet-up for Silent Rave New York. Wear your iPods and freak out the tourists by dancing to music only you can hear until your feet can’t take it anymore. London had a huge blowout in various parts of the city last year, so it’s our turn to wind it up. With hundreds—if not thousands—of fellow ravers moving next to you, it’s the one time you can feel good about following the crowd.
