Lulz, why?
And more recently we had a group of hammered 50ish year-old Canadian Pats fans try to start up with us a few seasons ago. And my group is probably one of the most low-key, non-threatening rows in the stadium.
I hate to generalize but they hop on the bus up there and are a mess by the time they get to the lot. Couple that with the im in a different country so I cant really get in trouble mentality, and its a bad recipe.
Not all are like this, have had far more positive experiences than negative with Canadian Bills fans. The bandwagon visitors though, different story.
