Washington D.C isn't one of our "biggest cities" it's not even close. It's less than one tenth the size of NYC (that's New York City sharp stuff). Almost none of the demographic (demographics measure facts about people slick) information in the post you called "well put" is remotely accurate. Did you mean "keep from" above? You have such a fractured sense of subject it's hard to tell what misconception you are trying to foist this time. If you ever got invited to a cocktail party you'd be beat to death without ever realizing it.
