Just echoing here . . . Hunter's Beach is a good one and well worth doing.

Stop and Smell the Flowers is a relaxing cache to do . . . can be quite pretty when the gardens are in bloom.

Bass Harbor Light . . . virtual, but picturesque.

On your way . . . Birdsacre Cache . . . definitely stop to check out the birds.

As for Boston . . . I've done some there, but none really stood out. I suppose I could mention the one where I had to move the rat trap to make the find, but well. . . .
