The Republic of Mammoth Cave is a very large, environmentally stunning nation, renowned for its avant-garde cinema, devotion to social welfare, and stringent health and safety legislation. The compassionate, democratic population of 423 million Mammoth Caveans are free to do what they want with their own bodies, and vote for whomever they like in elections; if they go into business, however, they are regulated to within an inch of their lives.

The large, liberal, socially-minded, outspoken government juggles the competing demands of Education, Welfare, and Administration. The average income tax rate is 51.5%, and even higher for the wealthy.

The sizeable but underdeveloped Mammoth Cavean economy, worth 11.7 trillion dollars a year, is highly specialized and led by the Information Technology industry, with significant contributions from Trout Farming, Cheese Exports, and Basket Weaving. State-owned companies are common. Average income is 27,653 dollars, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Imprisonment is the leading cause of disownment, the flight attendant who draws the short straw is on "cockpit bucket duty", the thin blue line is composed of picketing police officers demanding better pensions, and owning a really cute pet is grounds for immediate investigation. Crime is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Mammoth Cave's national animal is the eagle, which soars majestically through the nation's famously clear skies.

Mammoth Cave is ranked 126,345^th in the world and 630^th in the Outback for Most Eco-Friendly Governments, scoring 575.52 on the Dolphin Recycling Awareness Index.
