I'm a fan in the sense that I like to go to games, watch people, eat the stadium food and drink beer!
My DH is a fan and we're going to a Cubs game in Wrigley Field for "our" anniversary this year. 2 years ago, we went to Yankee Stadium for "our" anniversary. Luckily, both cities have plenty of other stuff for me - nice hotels, great sights, yummy food!
And I've never had a Chicago pizza....
Is that compromise or what?!
