June is the month of bursting colors and beguiling aromas, and now we are on the threshold of summer. The new season officially arrives a few weeks from now, but Memorial Day often is a truer marker of the Vineyard’s summer, and truer yet are the warm days and cool nights of early June. Sailboats glide in the distance on the blue depths of Nantucket Sound and the gaudy good cheer of colorful kites dart in the air above our beaches.
