Best of Boston

As the sun sinks into the rocky base of one of Nantucket’s oldest lighthouses, families wave as the ferry chugs by, fish- ermen cast their reels in ankle-deep water, and happy couples celebrate after the occasional surprise proposal. Want to see for yourself what’s making them all so jubilant? All you need is a beach chair and a bottle of something bubbly to toast to the happiest moments in life unfolding before you under a cotton- candy pink sky.
