Instead, you learn a set of rules that applies to all the numbers, and then the highway numbers themselves tell you how they run: One- and two-digit highway numbers less than 100 identify major routes (e.g., 1, 5, 70, 93) that cross state lines. Even numbers are east-west routes, odd numbers are north-south. Even numbers increase as they move from south to north; odd numbers increase as they move from west to east. Route numbers that are multiples of 5 are major arteries that extend over long distances. For example, I-5 is the westernmost major artery carrying north-south traffic between Canada and Mexico; I-95 is the easternmost major artery carrying north-south traffic between Canada and Florida. I-10 is the southernmost major artery carrying west-east traffic from California to Florida, and I-90 is the northernmost, carrying west-east traffic from Washington State to New York State. Three-digit numbers identify loops, or auxiliary, supplementary routes in or around a city. If the first digit is even, it is a route through or around a city that breaks off of and eventually rejoins the main route. If the first digit is odd, it is a spur into or out of a city and does not rejoin the main route (if you're afraid of getting lost, the auxiliary highways with an even-numbered first digit are thus always a safer bet). Generally, the second and third digits refer to the principal interstate served by the three-digit route. For example, if you are in Northern California and you find yourself on something called I-580, you can deduce the following:

It is clear (continues the general) that the United States must assume today the task that Great Britain performed so well in the nineteenth century--the protection of Western civilization from external danger.

anyone stupid enough to contemplate invading America would soon be forced to reflect on the fact that it contains hundreds of millions of guns, readily available to a population that takes its life, liberty and pursuit of happiness very seriously. In addition to the formidable US Armed Forces, there is the National Guard, state police and, as we saw on various occasions in 2015, an urban police force that can quickly resemble a military unit. In the event of an invasion, every US Folsum, Fairfax, and Farmerville would quickly resemble an Iraqi Fallujah.
