By land or by sea

You won’t be able to take in all 173 Trails & Sails events at 107 locations, but maybe you can manage 170? The Essex National Heritage Commission invites you to Cape Ann for whale watches and dory rides, Amesbury for house tours of famous residents including the Mary Baker Eddy Historic House, and Lawrence to reenact the Civil War era. How about the Essex County Mushroom Hunt to cap things off? Through Sept. 26 at various times and venues (outdoor events are weather permitting). Free.
