We are a family of 5 (2 adults and 3 teens) and are renting a house for a week in Harpswell in July. We're looking for suggestions for things to do. We are planning on seeing a show at The Maine State Theater at Bowdoin and spending a day at the beach (Reid State Park or Phompham). We would like to do something on the water (fishing, sailing, whale watching?). Any suggestions would be greatly appreciated.
