Welcome to the Geocachers of Long Island (GoLI) Geo-Art series.
The Geo-Art is modeled after the Montauk Point Lighthouse. It's the oldest lighthouse in New York State, authorized by the Second Congress, under President George Washington, in 1792. Construction began on June 7, 1796, and was completed on November 5, 1796. It is designated as a National Historic Landmark and still serves as an aid to navigation. And it's pictured on the GoLI logo.
This series is chock full of Long Island trivia, interesting facts, places, people and heritage. The questions are all multiple choice. If you're not sure of the answer, an internet search should make it easy. You can use the solution checker at the bottom of the page to confirm your answer. If you get it wrong, just try again. The hides are all very easy too, though are all hidden in residential neighborhoods. Please be stealthy, and if asked, explain honestly what you're doing. Once you find all 30, your Geo-Art reward will be completed. The caches are numbered in this series, the order that you find them is not important. Upon completion of this series, you will earn a GoLI Geo-Art mini coin AND earn the GoLI Geo-Art souvenir to post on your profile! The link to the GoLI Geo-Art souvenir is on the cache page of Geo-Art cache page #30.
Question #28: Commercial beer brewing on Long Island dates back to 1874, when William Becker opened the Hicksville Brewery. After operating for over 30 years, the brewery closed in 1905. In 1893, John Feller started brewing and bottling beer in the newly-named village of Lindenhurst, formerly known as Breslau. Feller ran his brewery until 1907, after which it changed hands several times until being purchased in 1914 by a German immigrant from Brooklyn, Otto Eichhammer. The Eichhammer Brewery closed after the passage of Prohibition in 1920. Long Island's modern beer brewing movement began in 1996 with the founding of two brewpubs in Patchogue and Southampton that continue to thrive today. Today(2020) there are more than 35 breweries spread across Long Island, and beer festivals can be enjoyed year-round. You can often fill your own 64 oz. bottles at the smaller breweries. What are these bottles called?
