It was a dark and stormy night when hundreds of crazy people lined up across the Brooklyn Bridge to create a flash wave. They came in droves, mostly young and adventurous. It was raining, freezing and windy, but the characters at Improv Everywhere didn't mind-- this is what they do.
My two crazy daughters braved the elements to join them. By the time they lined up across the bridge they were soaked, cold and having a blast. One umbrella blew inside out so they stripped off the material and used it as a rain hat.
