In 1982, the United States Border Patrol set up a roadblock and inspection point on US 1 just north of the merger of Monroe County Road 905A/Miami-Dade County Road 905A onto US 1 (they are the only two roads connecting the Florida Keys with the mainland), in front of the Last Chance Saloon just south of Florida City. Vehicles were stopped and searched for narcotics and illegal immigrants.
The Key West City Council complained repeatedly about the inconvenience for travelers to and from Key West. When the City Council's complaints went unanswered by the federal government and attempts to get an injunction against the roadblock failed in court, as a form of protest Mayor Dennis Wardlow and the Council declared Key West's independence on April 23, 1982.
On April 23 1982, Key West Seceded From The U.S., declared war, surrendered, and requested one billion dollars in foreign aid.
