100% on board with #2.1. The Giants. I have been a fan since the late 60s. I got to witness 3 championships last decade.
2. Any team other than the Yankees or the Dodgers. I live in Yankee country and Yankee fans annoy me (as do Red Sox fans) and the Dodgers should be self-explanatory.
3. Tampa Bay. My daughter is in Tampa and I usually make 1 or 2 games a year at the Trop (the worst stadium in Baseball east of the Oakland Coliseum - at least the bathrooms don't flood at the Trop)
