Oakdale is a scion of America's gilded age of a century ago, where powerful men of incredible wealth built South Shore gold coast mansions and dwelt in manorial splendor.
Oakdale Originated from a tavern owned by Eliphalet (Liff) Snedecor in what is now Connetquot River State Park. Soon after its founding in 1820, Snedecor's Tavern began drawing New York bluebloods and business barons who wined and dined in remote joy when they weren't fishing and hunting nearby. ``Liff's food is as good as his creek, a magazine writer declared in 1839, referring to the Connetquot River, ``and the two are only second to his mint juleps and champagne punch; whoever gainsays either fact deserves hanging without benefit of clergy. In 1866, as the railroad reached the area, Liff's wealthy patrons formed the Southside Sportsmen's Club, and soon the race was on to see who could create the most superb spread in the thick forests adjoining Great South Bay.
