Did you know that you can figure out how important your state was circa 1961 by adding up the area code's three digits, with zero equaling 10? It's because zeros used to take forever to go around the little rotary dial, while ones zipped along the quickest. The lowest possible code, 212, went to the busiest place, New York City. Los Angeles got 213. Alaska got 907. I guess Chicago didn't do too horrible for itself ending up with 312. At least we're no 702. That would be Las Vegas.
