Yes, everywhere. Last November I was in San Jose, Costa Rica, and doing a jog around the campus of the University of Costa Rica. I'm wearing a Bills t-shirt, and out of no where a hear an older Costa Rican man, yell to me "GO BILLS" and give a thumbs up. It was clear he was not fluent in English (and I am not in Spanish), we exchanged greeting and smiles over our favorite team. It was a fun moment. . . . Indeed, the Bills have an international fan base.
