I'm moving to Arizona, but I've been a lifelong fan of the St. Louis Cardinals. However, I've always had sort of a soft spot for the Arizona Diamondbacks. Should I make an attempt at becoming a D-backs fan as well, or would this be an act of betrayal? Is it possible to be a fan of both, or will I eventually find my loyalties horribly divided in an irreconcilable sporting identity crisis? Please help.
