Last month, late on Valentine’s Day afternoon, I went out to Chipman’s Cove to see if I could get some oysters. Normally I don’t bother going out so late in the season, since the recreational shellfishing flats are usually pretty well picked over by mid-February. But my son and my daughter were making dinner for us on Sunday and their sole request was to have some Wellfleet oysters, so I decided to try.
