On Cuttyhunk Island for my godson’s wedding—a joyous weekend of celebration, college roommate reunions, and even a wedding cake we somehow got there intact after a rocky ferry ride.During a break in the festivities, I grabbed my camera and headed for a solo walk on the beach. I was nowhere near the roped-off tern nesting grounds, but this protective parent still wanted to make one thing very clear: I was too close. Okay, okay! I’m going!
