The Pemaquid Beach Park snack bar is under new management due to the illness of the snack bar’s contract operator, Stuart Mason. The Bristol Parks and Recreation Commission ended Mason’s contract July 15 with the town making arrangements to pay him for equipment and current inventory. The snack bar’s staff have been transferred to the commission’s payroll and Bristol’s new parks and recreation director, Lara Sargent, will supervise the operation for the balance of the season.
