 The weather was hot, so were the sales at the recently concluded sidewalk sale days. That's the word from Greenwich Chamber of Commerce President and CEO, Marsha O'Kane. This supported our chamber theme of buy local, shop local, and it just made us very happy. It made the shoppers happy and the retailers happy. O'Kane says the four-day event drew big crowds to the downtown. Somebody told me Saturday afternoon, they said, look down Greenwich Avenue, feel the vibrancy. They literally said that.
