I live in San Diego and I've grown to become a casual fan of the Chargers. Not a rabid fan of the team, but I watch the games and root for them so long as they're not playing the Bills. My wife's family and most of my friends are big Chargers fans, so it's kind of come natural for me to root for them. I would never become a fan of a natural rival like the Dolphins, Pats or Jets/Giants. Definitely die-hard Bills fan for life.
