Disgusting display all around. I went to a preseaon "Pats and Rams" game a few years back in Foxboro with my girlfriend and her father expecting to tailgate and to be social. No one was straight out rude to us, but that was largely in part because we decided to stay to ourselves because the vibe from some of the fans was borderline hostile, or at the very least very unfriendly.
Between the long drive to get to the stadium, the horrible parking and traffic and time commitment and just the overall standoffishness of people. I never had any desire to go back to an NFL game again
