I was thinking David Flintstone was someone else who made up this name Flintstone (because what a funny last name!) but now I'm thinking otherwise. I'm not sure if this article has been posted from Island Distillers Facebook page https://www.facebook.com/pg/IslandDistiller/photos/?tab=album&album_id=957206677628410 . It has a good close up picture of Mr. Flintstone. On their Facebook page, it has a picture of the company making the foundation for their distillery. Here is an article on their Facebook page that gives more information about Dave Flintstone: He came to Hawaii as a bartender in 1989 and became a scuba instructor, then went to the Caribbean http://honoluluweekly.com/city-wise/2011/07/sugar-hi/ (I'm not sure if this Island Distillers Facebook page has been posted before or if this is new, I haven't seen it before).
