The town will hold its annual Independence Day parade and celebration on Wednesday. This year’s parade, which begins at 10:30 a.m. sharp, will feature four marching bands, nearly a dozen floats, clowns, an engine and three-car train, several color guard units (including a ranger unit from the US Army Corps of Engineers), antique cars and fire engines, three military vehicles, and several marching groups representing local sports and civic organizations. The parade will form behind Storage Unlimited on Terry Avenue and proceed along Route 3A toward the town common. The celebration will take place on the common immediately following the parade, at about 11:30 a.m. It will feature free pony rides for children, a dog show, live music, and inflatable houses for children. Antique cars and the three winning floats also will be on display, and there will be free train rides and refreshments for purchase. The parade and celebration are being organized by the Burlington Breakfast Rotary Club.
