From the "Facts that may only interest me" department:
Approximately 2 million people will crowd Washington Mall in an effort to try and witness history. To put a perspective on that number (especially for the square footage of the mall), that number is larger than the
population of the following states:
New Mexico
West Virginia
Nebraska
Idaho
Maine
New Hampshire
Hawaii
Rhode Island
Montana
Delaware
South Dakota
Alaska
North Dakota
Vermont
Wyoming
In fact, you could take the population of our largest state and add the populations of the decently sized states of North and South Dakota and still not reach the number of people that will be in that relatively small tract of Washington D.C. as I write this.
