Here’s a very nice recollection of bare feet on Martha’s Vineyard.
It’s entitled Going Barefoot — An Island Specialty and chronicles how so many went barefoot there during the 1960s, including pretty famous folks like Art Buchwald and Mike Wallace.
It also pretty much reinforces what we’ve already figured out&mash;that NSNSNS signs only really appeared during that time. It took longer on Martha’s Vineyard, but it came nonetheless.
I do believe Island retailers – the majority of them off-the-grid counter culturists themselves; why else would they be here?! – were late to tumble to the what-the-hell? attitude of merchants on the mainland who were busy tacking up NO BARE FEET signs. But eventually they caught on, and gradually hippies grew up and accepted jobs in the banking industries and bought Beemers and put on shoes (not necessarily in that order).
I suspect this is typical of other resort-type areas with water around. They managed to resist the shoes-required wave for a while, but eventually succumbed.
To our, and their (I believe), detriment.
