I am a Miami homer with all teams - every other team can rot in **** as far as I care.
I'm even OK going for FIU as long as they are not playing UM. The games over there are fun, it's a different kind of experience, like glorified high school ball.
The ONLY out of town exception I hold somewhat is for the Atlanta Braves. Obviously, as a kid in the 1980s, the Marlins did not exist, and I liked baseball. We'd just gotten cable in the early 80s when it was this new big thing......and which team was on TBS constantly? Yup, the Dale Murphy-era Braves. I'd pretty much watch the Braves all summer. I don't know, I guess I don't even have much attachment to them anymore, I kinda stopped caring when Glavine/Maddux/Smoltz retired.
