Tugboats to pedalboards, Snoopy to Frosty and all colors in between. The Mystic River lights up with a floating celebration of the season from boaters around the region. Thousands crowd the shoreline and the light show begins with the sound of the drawbridge horn. Sponsored by the Greater Mystic Chamber of Commerce, the holiday lighted boat parade is a MysticView not to be missed. Every year on the Saturday after Thanksgiving.
