Not really that important, but I haven't seen anyone mention it. in the Northern VA/DC area, McLean, VA is synonymous/interchangeable with Tysons Corner, VA.

Tysons Corner's motto is 'America's Next Big City'. Home to lots of corporate headquarters, Geico, (((USA Today))), etc. In recent years had the DC metro build a subway line out towards it. Lots of intel agencies with unlisted properties (Langley, VA is also just down the street). Massive sex trafficking hub as well.
