It CAN be done and HAS been done before- in 1982.
Here's the story:
I used to live in Key West, Florida- the last in a series of small islands in the Gulf/Atlantic. It is located 90 miles from Cuba- closer in destination than Miami.
There are more bars, per Capita, in Key West than in any other US City. I used to own an upscale piano bar there.
Tourism is the main source of revenue. It also operates a major Coast Guard facility.
The Florida Keys are often also referred to as the Conch Republic, formed in protest of their treatment by the US Government when the Feds stepped in and decided to put roadblocks up between the Keys and the Mainland one busy Easter weekend. People were required to show passports when entering or exiting to prove their American citizenship.
Many tourists who were going to spend a long weekend in Key West were not prepared to show a passport and turned to return home.
That weekend cost small businesses throughout the Keys to suffer a severe blow to the economy and in general, pissed them all off.
The Mayor was so angry that he said, "If they're going to treat us as a foreign country we will secede and form our own Republic"
He then seceded, declared war on the USA and a minute later surrendered in order to receive federal aide.
The "Conch Republic" still issues passports to this day which are legitimate and accepted as official US passports throughout the world.
I actually brought my Conch Republic passport (along with my US Passport- just in case) when traveling to England, and other countries and never once did I have to use my Federal passport. My Conch Republic passport was accepted and stamped at each destination.
I'll post this under it's own title as well, in hopes that states seriously consider seceding. If we had 50 individual states there would be absolutely no more federal government to mess around with us. O and company could no longer control us- much less classify us as Domestic Terrorists because we would no longer be consider "Domestic".

The Conch Republic ~ We Seceded Where Others Failed
A BRIEF HISTORY OF THE CONCH REPUBLIC
The Conch Republic was established by secession of the Florida Keys from the United States of America, on April 23rd, 1982 in response to a United States Border Patrol Blockade setup on highway U.S.1 at Florida City just to the north of the Florida Keys. This heinous act effectively isolated Keys Citizens from the U.S. mainland since the blockade was on our only land artery to and from the mainland. This roadblock portrayed Keys residents as non-U.S. citizens who had to prove their citizenship in order to drive onto the Florida mainland! Hardly an American thing to do!
We protested! A totally American thing to do! Key West Mayor Dennis Wardlow along with a few other 'key' Conchs, went to Federal court in Miami to seek an injunction to stop the federal blockade, but to no avail. Upon leaving the Federal Court House , on the court house steps , Mayor Wardlow announced to the world, by way of the assembled TV crews and reporters, that ; "Tomorrow at noon the Florida Keys will secede from the Union!"
At noon, on the day of secession, at Mallory Square in Key West Florida, Mayor Wardlow read the proclamation of secession and proclaimed aloud that the Conch Republic was an independent nation separate from the U.S. and then symbolically began the Conch Republic's Civil Rebellion by breaking a loaf of stale Cuban bread over the head of a man dressed in a U.S. Navy uniform. After one minute of rebellion, the now, Prime Minister Wardlow turned to the Admiral in charge of the Navy Base at Key West, and surrendered to the Union Forces, and demanded 1 Billion dollars in foreign aid and War Relief to rebuild our nation after the long Federal siege!
Thus began our Conch Republic journey which still continues today! We are both Conchs and we are Americans and we are proud to be both. By act of Congress we hold dual citizenship as Conchs and as Americans and will fight for the right to be both!
Contrary to recent reports, the name "Conch Republic" refers to "all"of the Florida Keys, or, that geographic apportionment of land that falls within the legally defined boundaries of Monroe County Florida, northward to "Skeeter's Last Chance Saloon" in Florida City , Dade County Florida, with Key West as the Nation's Capitol and all territories north of Key West being referred to as "The Northern Territories". Be it known that these boundaries were established by the U.S. Government when they set up "THE" Border Patrol blockade in front of "Skeeter's Last Chance Saloon", in April of 1982, thereby establishing a new United States border!
To enforce the validity of our secession, the Monroe County Commission, in 1994, by unanimous vote, did pass a County Resolution recognizing Mayor Wardlow's actions, on the 23rd of April in 1982, as by, of and for the people of the Florida Keys. Read the full story!

In the quest for recognition, the Honorable Peter Anderson, Secretary General of the Conch Republic has created "Official Conch Republic Passports" . The Secretary General has extensively traveled our surrounding Caribbean Nations with nothing more than his Diplomatic Passport and has been well received by many as a Diplomat and as a Government Official of the Conch Republic and even had his passport endorsed by nearly all! Officially, our passports, Diplomats and Citizens, have been well received by 13 Caribbean Nations as well as Germany, Sweden, Havana, Mexico, France, Spain, Ireland, and Russia.
