Along this shore, we have maybe 3 or 4 regular swimmers.
One stranger has come by in the past week apparently determined to live a death wish. My neighbor tells me he swims a sharp turn in front of his place, and swims the ¾ mile across Winter Harbor!

There's no accompanying boat.
He can be identified by a white float that he drags behind his back. It's about the size of a loaf of bread—or a sea gull...
That's all you can see.

The NHMP hasn't been seen for a couple of weeks here, so perhaps boaters who see this swimmer would advise him accordingly.
Winter Harbor is still being used as a race course for ocean-racers, Scarabs, Fountains, Baja and Donzi—and seeing especially "heavy use" since Thursday.
