Heres a thing most people overlook, but I notice it a lot being English in America: Clothing with place names.
It seems EVERYONE here at University owns at least 5 different items of clothes with a big place name across the front, be it from my current Uni, their old high school or just some place they visit a lot.
It's very odd.
Oh, yeah, this is fairly common. Usually it's the school someone goes to or a city they've visited. It probably doesn't seem weird to me that people have this kind of pride in where they go because the general 'American pride' thing is so pervasive as well. Might as well just be proud of everything else too, I guess!
