>North Dumpling Island
In 1986, Dean Kamen, inventor of the Segway and founder of FIRST, purchased the island for US $2,500,000.
After a denial from local officials to build his own wind turbine on the island, Kamen "seceded" from the United States. Although Kamen's secession is not legally recognized, he still refers to the island as the "Kingdom of North Dumpling" and has established a constitution, a flag, a currency (the dumpling), a national anthem, which is a parody of the song "America the Beautiful" written by Paul Lazarus, and a navy consisting of a single amphibious vehicle. The people of North Dumpling are called "Dumplonians", and Kamen is said to refer to himself as "Lord Dumpling" or "Lord Dumpling II".
