I came to the US in September 1990 as a postdoc at the University of Rochester. Each week on Monday, my coworkes in the lab would have lengthy discussions about the "Bills". I got curious and started to watch football on TV. Initially, it did not make any sense to me. After Superbowl XXV, the game, and the Bills grew on me, and I have been a Bills' fan since.
In 2003, we moved to Texas. My son, although he was only 4 at the time of the move, is a staunch Bills fan.
