The one's on Wachusett do make a low pitch hum, from a distance not a big deal but from close by or under them, I can see where that would grow old for residents. From a distance on some summits, Greylock, for instance they don't bother me but then I never consider North Adams as a vacation destination. (Plymouth & Cardigan aren't on that list either)
That said, Lincoln, Bartlett, Glen, and much of the ADK High Peaks & BSP I would consider vacation worthy. (maybe I just need to be more than 3 hours from home) Just the name, Saddleback Ridge caused panic as I think that summit may be the best 4,000 summit in ME outside BSP.
Vacationing at the shore, like I do, I wouldn't be bothered by seeing them a few (okay, maybe several) miles off shore. I can't see it effecting vacation rentals much. For the affluent who live there & have the clout to whine about it to those who make decisions..... (Don't cross that line)
If they could come up a 50 -80 foot model that they could line the main highways with, would it ruin your trip on the Mass Pike, 84, 91 or 95 or others in Southern New England? (you could stop in Westfield on the Pike, Portland on 95, Hadley on 91 going North & 8 south at Waterbury (or just beyond). 290 & 495 would be fine all the way except maybe on close to the Cape if you wanted to give beachgoers the same courtesy as mountain vacationers. They's be cheaper to make & you could put a few hundred or more on each highway. (every 1/2 or 1/4 mile)
