They've done quite a bit of Google street view throughout Fairfax already.
Pretty much everything inside the Beltway is done. And a huge portion of the rest of Fairfax is complete. Easiest way to see what has been done already is to go to Google Maps and and drag the little yellow man icon (located above the zoom in/out bar) and as you drag the man onto the map... everything that has been done with google street view turns blue.
