I was missing the Cape so I spent an afternoon mostly in Wellfleet, where my family used to own a cottage by the ocean. We spent at least two weeks a year there and many weekends.
For January, there sure was a lot of traffic going both ways on my way home. I guess some was normal, but maybe I wasn't alone with the idea of a winter day trip. It sure was a nice day for it.
Cape Cod - Not just for summer anymore (but mostly, since most of the touristy shops and restaurants were closed for the season).
