Beating the heat, if it ever comes
“The Swimmer” (oil on panel), by Lee Roscoe, at the Cahoon Museum of American Art, Cotuit, Mass. The painter is based on Cape Cod. When you think of swimming on Cape Cod, you think of beaches but there are many fine fresh-water kettle ponds to swim in on the peninsula, and the water is a lot warmer than the ocean and bay water.
