Residents of the Lower East Side were treated to a half-hour of window-shaking motorcycle noise pollution last night, as one or two guests of the neighborhood repeatedly traversed Orchard St while revving their unmuffled engines. The fact that the police never showed up indicates that the standard for noise pollution in Hell Square has climbed to obscene decibels. It's time to change that! Dial 311 the next time the noise enthusiasts treat our neighborhood like there personal playground!
