In "Howard's New Life" (1967), a later episode of "The Andy Griffith Show", Howard Sprague sees a tropic isle on a teevee travelogue show, and decides to chuck it all and move to an island in the Caribbean.He winds up on the fictional island of "St. Benedict", which is only accessible by boat from Trinidad, and soon meets the island's friendly store-owner (played by the great Harry Dean Stanton, left).
Turns out that Harry's store is full of derelict Howards who moved to the same island before Howie did, and are now reduced to building ships in bottles. Click post title for imdb info.
