I note in regard to this, and some other threads, that the reference to Florida in a shanty is reasonable because Pensacola, Florida was long a major sea port and naval base. One could pick up cotton in Pensacola as well as Mobile, only some ninety miles away. Depending on the antiquity of the song Florida might have included Mobile as the entire north gulf coast was once part of Florida and or Louisiana, depending on what maps you believe. Pensacola, unlike Tampa, which was also a fine port, but not a rail head.
