Me and a buddy are going to be coming to the Cowboys game from Edmonton, Canada, so I was hoping I could get some tips on tailgating. What is the best place to tailgate before the game? I've read about purchasing parking passes for tailgate areas, but we don't plan to drive, so can we just walk into these areas? And I'm guessing we can just bring our own beverages and join the party? I'm not sure how the details work and any help would be appreciated.
