Most places it is safe to do so.
Eagles fans are a special kind of stupid...............
I’ve traveled to many NFL stadiums in support of my team— each time wearing purple/white. We act in a civilized and respectful fashion. Even during/after an heated overtime playoff game which ended with our tight end blatantly pushing off to score the winning touchdown, have never experienced anything that seemed threatening or dangerous except for Philadelphia.
It didn’t matter that the Eagles were having an easy time of it— there were many fans (and we were in very expensive seats and had car service) that needed no provocation and have ever since made me wish the entire city burns to the ground. I will never return to that city and do wish ill upon every fan and franchise. Which is a shame because I did respect and like the Flyers…
