I remember, in the mid 90s getting up at 6:00 am, taking a taxi to LGA and catching a 7:00 am Shuttle to Washingto DC so I could be at a 9:00 am meeting.
In part, that was partly because you could just walk on the next shuttle at 7:30 or whenever if you got delayed for some reason. Personally I'd probably take the train although a 9AM meeting might be tight.
6am is about the time you'd need to get up if you lived in Front Royal and wanted to make a 9am meeting and that's assuming a pretty efficient workflow for leaving the house.
