Hi - not sure if you found anyone yet, but myself and another coworker of mine work in Tysons Corner near the Tysons 1 mall on Westpark Dr. and are commuting in from exit 130 in Fredericksburg. We are looking for a 3rd person to take turns driving to be able to have HOV all the way up.
Is this something you are still looking for? Perhaps we could meet at the exit 140 commuter lot?
