The Lower East Side is about to get cool again, at least for a couple of days. On February 4th snowboarders will start taking practice runs down the ramp that's being built on the side of the East River (you can get a nice view from the Williamsburg Bridge right now). Then on February 5th they'll compete in an hour long contest, followed by a 7 p.m. Anthrax concert, followed by another hour of riding for the finalists. Here's a look at how the ramp (and snow making) are coming along—would you take a ride down this?
