Question: Which Florida island got its name after a developer claimed to have discovered a treasure chest full of Spanish doubloons?
Answer: Treasure Island
In 1918, a developer named W.D. McAdoo claimed to have discovered a treasure chest full of Spanish doubloons on an island off St. Petersburg, where he was planning to break ground. The supposed find spurred interest not only in his island but also in a nearby one that developers quickly rechristened Treasure Island.
