Football: Bears. *sigh*
Other sports I passively follow. I basically root for Chicago to win. I used to be into baseball when I was a kid, and it is a huge sin to root for both the Cubs and Sox. I take great pleasure in doing that to piss off local people. I was also caught up in the Bulls (basketball) mania in the 90s. It helps when Micheal Jordan is on your team. I used to dislike hockey because I worked in an ice arena and just got burnt out on that culture (as well as figure skating culture), but I have grown to appreciate the Blackhawks and the sport in general.
