I am from DC, although I've lived in Northern VA (NOVA) more than DC, and moved to GA 2 years ago. I will probably be back in NOVA. The biggest factors are affordability and school systems. I've got 2 kids (one going to 3rd grade and the other turning 2 soon). I prefer Alexandria/Arlington/Springfield/Annandale but would go as far as Fairfax/Burke. I also like Chevy Chase/Bethesda in MD but that area is a little more expensive. I am not looking in DC at all.
What about you?
