A quick overview of the Sunshine State's fascinating past, with photos and illustrations included.   In 1513, Spanish explorer Juan Ponce de León first set foot on Florida's east coast. The land he discovered was a geographic anomaly so distinctive that one day, centuries later, astronaut Neil Armstrong would say that Florida was the first shape on earth he recognized on his return from a visit to the moon.   This unique state has witnessed such momentous events as the 1959 arrival of the first Cuban exiles under Fidel Castro and the 1981 launch of the Columbia--the first space shuttle. Join historian James C. Clark as he chronicles the surprising history of the Sunshine State in this concise and captivating book.
