The White Lined Wall of I 15 is a gargantuan, cultured nation, ruled by Eisenhower with an iron fist, and notable for its vat-grown people, pith helmet sales, and state-planned economy. The hard-nosed, cynical, humorless, devout population of 11.532 billion Highwaymen are kept under strict control by the oppressive government, which measures its success by the nation's GDP and refers to individual citizens as "human resources."

The large, corrupt, well-organized government juggles the competing demands of Administration, Defense, and Education. It meets to discuss matters of state in the capital city of Butte. The average income tax rate is 68.7%, and even higher for the wealthy.

The frighteningly efficient Roadworthy economy, worth a remarkable 1,420 trillion tolls a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. However, for those in the know, there is a large, well-organized, fairly diversified black market in Arms Manufacturing, Information Technology, Uranium Mining, and Woodchip Exports. The private sector mostly consists of enterprising ten-year-olds selling lemonade on the sidewalk, but the government is looking at stamping this out. Average income is an impressive 123,157 tolls, and evenly distributed, with the richest citizens earning only 2.3 times as much as the poorest.

Children often kick cougars for amusement, men who wear pink are seen as dangerously unmanly, there is a growing belief that consciousness is a simulated illusion within a computer-generated reality, and it is universally agreed that the first 31 issues are the only ones with humor and charm (I 15 has found 2 easter eggs). Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. I 15's national animal is the cougar and its national religion is White Line Fever.

I 15 is ranked 48,810^th in the world and 2^nd in Montana for Lowest Crime Rates, with 74.53 law-abiding acts per hour.
