We're contemplating a stop in Boston this summer. I know there are some nice harbor islands where we could anchor that are classified as parks, and we'd probably do that -- but what are the best choices if we wanted to spend a night or two at a slip to take advantage of the in-town activities? Are there good (cheaper) places with moorings and dinghy docks or would we have to take a slip? I haven't even looked at the cruising guides yet. Will also check activecaptain.com, but I figure someone here can help clue me in.
