Long Key is in the middle Florida Keys about halfway between Islamorada and Marathon. It is home to a small village, Layton (population about 200), and Long Key State Park, a popular camping destination.
Long Key might have remained largely unknown except for its fishing camp known as the Long Key Fishing Club. Members of the club included Zane Grey, Herbert Hoover, Andrew Mellon, Franklin D. Roosevelt, William Randolph Hearst and many other famous people.
