Hey Eric. I have to tell you that I was confused (and probably still am). I went with pure population numbers because I found the 'metro area' numbers to be kind of nebulous (Like Phoenix. The metro area is now larger than Chicago). I was surprised to learn that Jacksonville has more area than any other city. I always thought that LA held that title.

So. I had to pick a number to work with and tried to remain true to that. I'll try to explain a little better when I get to Geography and populations.
