Lol funny you should mention this. I live in Toronto, which is the land of many NFL fans since we don't have our own team(Contrary to what you may hear, we have only SOME Buffalo fans, not as many as they tried for).
Anyways, I have a few Cowboys decals on my car, and I get really excited when I see somebody else with one(some) as well. I think about honking at him, but I always think he's gonna mistake me for a road-rager, so I resist. I did join a new beer-league baseball team a couple years ago, and I actually met about 7 new Cowboys fans on that one team, compared to the maybe two I had met in my previous 31 years of living. If they are playing well, I'll let it be known. If they are losing, I'll let it be known in a lesser kinda way.
