Well, I must admit that I have allegiance to 2 teams. I was born and raised in Cubs country, and like other Cubs fans, once a fan, always a fan.
Then I lived in Sacramento for 23 years (the majority of my adult life). I became a Giants fan full time (even though I loved them from the Willie Mays/Bobby Bonds days.).
Now, I am back in Cubs country (with every intent to return to Sacramento, as soon as I line up a job). It has rekindled my love of the Cubs (although it never left...they just became my #2 team).
So, all of that is just to say that my #1 team is the San Francisco Giants and my #2 team is the Chicago Cubs.
