How do I get the full FedEx Field experience?

I highly doubt you'll get anything signed from the opposing team. If you want to go down on the field during warm-ups, just walk around until you find a cool security guard to let you down there. Some of them are jackasses and won't even let you go a few rows down to take pictures. A lot of times, find one who is busy and just walk down there like you know what you're doing. I haven't seen them sign anything before the game at all, so I'd wait until afterwards.
