I am in Florida now and used to live aboard in Boston harbor, but that was about ten or so years ago and things have probably changed a lot since then. My family is mostly on the Massachusetts north shore, Beverly, Danvers, Marblehead, but my kids live in New Hampshire and Connecticut, though the Connecticut is also heading north, probably Lynn or Salem.
Anywhere from Narragansett Bay to southern Maine, as long as there's shelter from Nor'easters, would work for me. I'll have a little car and will be able to visit my kids and grandkids easy then. Grandkids seem to grow so fast.
