Newburyport: Shoppers at the Newburyport Farmers' Market were treated to some unexpected entertainment Sunday, when more than 80 dancers converged for a flashmob dance to promote beachfests.org and Summer 2011 at Salisbury Beach, which kicks off with the Sand and Sea Festival June 25-26. The non-profit Salisbury Beach Partnership, which produces the summer event series, organized the flashmob with support from Cedardale Health & Fitness and ZUMBA with Tracey at the Dance Place.
