Coming from beautiful, friendly, cold Northern Michigan, I'd be ecstatic to get out of the DC area, but good luck moving the other 10,000 NASA employees.
It's a different culture in the Midwest. Some good, some bad, but overall I personally prefer the ability to have friendly conversations with strangers back home than the (generalizing here) awkward, egotistical, self-interested metropolitan area here. The first questions you are asked in DC are inevitably "Where do you work?" and "What's your title?". That being said, DC is a beautiful city and there's a lot of great things here.
But still, I'd much prefer to be camping on a beach on Lake Michigan...
