I'd probably lay low and not really cheer/boo either team (well maybe boo the Cubbies since it's in St. Louis). I personally think it's annoying when fans of neither the Brewers nor who they're playing wear their teams stuff to Miller Park and cheer against the Brewers, and yes it's mostly been Cubs fans but I'm sure there've been others. I've been to a handful of Cubs games at Wrigley, none of which were against the Brewers, and I just sit their contently rooting against them in my head, but not cheering obnoxiously when the other team does something good. I'd rather not start a heated arguement or be berated, which could happen no matter what park you're at. That's just me, though http://forum.brewerfan.net/images/smilies/smile.gif
