Let's just quote CSN Bay Area's Andrew Baggarly here:

There's a Brewers fan nicknamed Front Row Amy who is very attractive and has generated quite the following here in Milwaukee.

And on Deadspin!

But I think the better representative for the local folk is the portlier, apparently inebriated college-aged gentleman who wore a yellow banana costume with "Rally Banana" on the front.

(The Brewers salvaged an 8-5 win over the Giants.)
