I liked your post for everything above the second picture.I have noticed that some Brewers fans--certainly not all, and not any that I've seen here--are quite salty these days about the Cubs. An inferiority complex, perhaps? (For the record, I think Milwaukee is a lovely town, and the design of their art museum is cool as hell!)
It's not an inferiority complex, it's a reaction to the bandwagon Cub fans. They are obnoxious and rude. I know that they are in the minority, as I've met many die hard Cub fans. I've been to Wrigley for a Brewer game, and the fans were incredible. But up here, we see the bandwagon fans much more often. Going to Miller Park when the Cubs are in town is not a fun experience.
Unfortunately, too many Brewer fans are acting the same way. As for me, I'm much more salty about the Cardinals. But that's another story.
