Going to be there from this Thursday afternoon until Monday morning so no chance of getting a pass mailed to me.
Will probably require more than a day pass and since I've got the small matter of a marathon at the weekend, will be heading out towards the Pentagon at around 5:30am on Sunday. It's recommended to have a pass already in place due to the amount of people travelling back and forth around that time.
My flight from DCA is around 11:15am so wll probably leave my hotel before 9:30am to catch that.
