Florida was never in The Colonies.

In 1763, under the Treaty of Paris, Spain gave Britain control of Florida in exchange for Havana, Cuba, which the British had captured during the Seven Years' War (1756 through 1763). That same year, the British built a fort overlooking the entrance to Pensacola Bay. Spain captured Pensacola in 1781 and regained control of the rest of Florida in 1783, when Britain gave Florida to Spain in exchange for the Bahamas and Gibraltar.

And Miami still acts and feels like a Colony of Spain/Cuba
