In the evening, too. People who remember when Cape Cod had real seasons, because it didn’t have a substantial year-round population, remember what it’s like to be in a lonesome cottage by the shore before the tourists show up. The tourists live there all the time now. And it’s never cold because the houses are modern and weather is something you watch on television.
The old-fashioned locals know that summer doesn’t begin, really, until July Fourth. Memorial Day is a head fake. You might as well swim at the Arctic Circle as Nauset in May or June.
