Take a boat tour of Great Bay in Margie and Peter's 19' power boat.  Up to four guests will board the boat on the Oyster River in Durham and cruise through Little Bay and Great Bay, perhaps going up the Lamprey to Newmarket or the Swampscott to Exeter, depending on the tide.  Picnic lunch is included.  We will find a mutually acceptable date through October, 2012 or from May to October, 2013.
