By all means, if in the Mystic area, DO see the Seaport; we did a couple of summers ago after the Deep River Ancient Muster (Fife/Drum) and although a little pricey, it was terrific. Got a chance to meet and breifly sing with one of the Chanteymen of "Forebitter" who puts on a very enlightening and enjoyable program with his banjo, then got a demo on board an 1840's whaling ship of the chantys being used during various operations of the rigging, windlass etc..
We missed Portsmouth; the idea got overruled by Matronly edict, and we went to check out lakeside property in the Winthrop area - the foliage was lovely - instead. Just as well, as me leg has some healing yet to do, the knee was "out", and the hike from parking to music sites might have been irksome. I wouldv'e liked to seen that B-17, though; that's one awesome airplane! We do live in a noisy culture, here, and I have a little problem competing with blatting macho-bikes and punk-o boomcars. That's no so much an issue with the F&D Corps; we tend to set off car-alarms along the parade route with the concussion of the big bass drum, and mics and amps are never required! Next year perhaps they can arrange things to be a little more considerate of "traditional" musicians and those who still like to hear it (the "quiet minority"?) How about more bugles and bagpipes? We don't need no stinkin' electronics to make a bloomin' racket!
