Not to mention that nearly every sports bar in Milwaukee has a shuttle(they usually require you to buy some drinks/food) that takes you to and from the game. Kelly's bleachers, Derry's Pub, Mo's Irish Pub, Long Wong's off the top of my head. Not to mention some of the hotels do it as well(ambassador comes to mind). The Casino does it too.
