Mayor Mike is nutty as a fruitcake. No smoking within 400 miles of a school zone, no trans fats, no jaywalking (okay, that one was Rudy…) Now the too-rich-to-be-called-nuts mayor is calling for windmills to top the city’s skyscrapers. Not since they put a mooring tower for dirigibles on top of the Empire State building has there been a nuttier idea in NYC, the land of nutty ideas.
