The tide was dropping and Kaare, our 10-year-old son, waited for it to get low enough to skim board. Four or five people were swimming. Three police boats (at least) and a Coast Guard boat were sitting together a thousand feet or so off the beach, responding (I learned today) to a 12:30 p.m. call that a swimmer was in trouble. We could see divers in the water, and for a while a helicopter hovered high above the mouth of the Saugatuck, west of Compo, but there wasn't much other activity.
I used my binoculars to scan the water from Fairfield in the east and south to the Compo jetty -- I did it three times between roughly 2 p.m. and 4 p.m., and counted 45 sailboats, 50 sailboats, and 47 sailboats. By the time we left, the sun was low, the water was almost purple, and the shadows were long.
