“If the Vikings win, yes, I would take off any sort of like colors. I know it sounds ridiculous, like we’re almost talking about gangs here, but it’s no joke down in Philly. It really isn’t,” said Drew Baydala, with Ticket King.

“I would advise you not to be over inebriated because they will be,” said Steve Erban, with Creative Charters.

Creative Charters is charging Vikings fans $700 per person to make the trip.
