Twenty-five years ago a very good idea was hatched by the folks at Grace Church in Vineyard Haven. The results of that idea can be seen every Friday evening during the summer as lines stretch down the street, past the ferry, out to sea and culminate as far away as Provincetown or Gloucester.

Okay, that may be a bit of an exageration, but why should fish tales have all the fun. This is a lobster tale after all.

The idea, of course, was to sell lobster rolls to help fund the church’s good works. But they don’t sell just any old lobster rolls. They sell the best lobster rolls.

This Sunday at 2 p.m. at the Vineyard Haven library, lobster roll experts Lorraine Clark and Beatrice Green will pull back the curtain on this Island institution. Come out and learn the history, hear the stories and learn how to make a better lobster roll.

Alas, no lobster will be served. Just cookies and cider.
