The question of when spring arrives on the Vineyard is a matter of debate. Some consider spring underway when the first pinkletink peeps or the first osprey soars over the Island. The best indication of spring's arrival is color: the drifts of bright yellow daffodils, some planted more than a century ago, that grace the rolling hills and roadsides of the north shore, and the vibrant emerald green of lawns and farm fields from Aquinnah to Chappaquiddick. Year in and out, the Vineyard explodes in color around May Day, last Friday. As May opens, the world comes alive again. Spring has arrived.
