Holiday cheer was brimming in every corner of Edgartown as Christmas in Edgartown festivities were underway Saturday. The annual Christmas parade rolled down Main street at 11 a.m., ending with the arrival of Santa himself atop a big red Edgartown fire truck. Festivities continued with gingerbread house-making, a family dance-o-rama, the great chowder contest, and a host of other activities that mark the season.
