Wikipedia: San Ysidro is home to the world's busiest land border crossing, where U.S. Interstate 5 crosses into Mexico at Tijuana. In the 2005 U.S. fiscal year, more than 17 million vehicles and 50 million people entered the United States at the San Ysidro port of entry. The great majority of these are workers (both of Mexican and U.S. nationality) commuting from Tijuana to jobs in the greater San Diego area and throughout southern California. There is also a thriving reverse traffic, both of workers traveling to maquiladoras in Mexico and those purchasing services (vehicle repairs, hair and beauty services, childcare, medical or dental) or seeking entertainment in Tijuana. Crossing times are often slow at San Ysidro, particularly for those entering the United States in cars. For this reason many cross on foot, the line for which is frequently much faster than the vehicle line. Some foot travelers own a car in each country, and keep them in one of the large parking lots located near the border post, or use the respective public transportation systems of both cities (both systems have a bus station built solely to serve the border crossing point, and the San Diego Trolley runs from downtown San Diego to the border crossing).
North America includes Mexico, the United States, Canada, and Gotham City.The region temporarily existed as a Protectorate of His Imperial Majesty Emperor Norton I, with its capital being the city of San Francisco. Sadly, this term of benevolent ebullience lasted a brief two decades and ended c. 1880.The United States is now the dominant country of North America. It arose as a nation only 225 years ago after a successful rebellion against the British government under King George III. From a distance, it appears that the eastern coastlines of North and South America fit exactly into the west coast of Africa. In fact, about 250 million years ago these continents really were all connected in one land mass that we have named Pangaea.With such a foundation in tectonic unity, there is no doubt that someday soon the people on every continent of earth will realize their fundamental similarities.
