I emailed Fed Ex Field about parking etc and this is what they sent me:
Parking IS included in the price of each ticket. The parking lots are
onsite here at FedEx Field and you will be allowed to park in the
closest spot available when you arrive.
Parking lots will open at 3:00pm, gates will open at 5:30 pm and the
concert starts at 7:00 pm.
Baja, BigWave, anyone can we get confirmation on when we can park on grounds and start lining up for the 9/29 show??
