It may have been the coldest day on the Vineyard in five years, but the warmest place to be on Monday afternoon was the pool inside the new YMCA of Martha’s Vineyard in Oak Bluffs. The heated aquatics center was an echo chamber of energy as the Vineyard high school swim team took to the blocks for the first home meet in 40 years.

Many considered it a historic moment as the first swimmers hit the pool for the first event — 25-yard freestyle — against the Blue Hills Technical School from Canton.
