Yes, the Sunday night after Thanksgiving. It snowed pretty good but nothing crazy. I think there was like 4 inches total overnight.
We were treated incredibly there. We would be invited to tailgate after tailgate for shots, beers, and food. Very nice and generous people there who knew just the right amount of smack to talk to keep it fun while being very hospitable.
The old Metrodome was the same way. They are smaller towns, not sure if that is why they are friendlier. And that was at least 25 years ago. Never got to go to Lambeau, but it sounds similar. Soldier Field was an experience I will never forget, but the tailgate was down right scary. I took my Lions jacket off and froze my ass off just to survive. Finally bought a Snoopy XMas sweater, which gave them another point of attack. Those guys were brutal. But the stadium was awesome. You could feel the history.
Brother in law is a Phi fan. He claims that the tailgaters are top notch. No one can explain how these same fans transform into thugs the second they walk through the doors? Chicago, IMO is just as bad, but they start in the parking lot.
College tailgaters are the most passionate. Love these people.
