Note: The USA is the last country in the world that still uses the ancient Roman imperial system for measurements (miles, feet). When you look at pictures of signs, multiply by 1.6 to obtain distances. (Trivia: Ethiopia is the last country in the world that still uses the Julian calendar. So if the USA and Ethiopia merged, you would be brought back 2,000 years to the age of the Roman empire).
