 Greenwich Chamber of Commerce President and CEO Marsha Cain has the four-day event kicks off today, and she has this advice. First and foremost, I would say wear your comfortable walking shoes because Greenwich Avenue is on a slope up and down, and you're going to want to go to both sides. As far as parking, have a game plan. Again, go on our website or go to the town website, and you'll look at the parking maps, which are all 12-hour parking areas.
