Yeah, it is a recent change. That said, my friend did manage to go, and that was in February, so they do make exceptions. If you've got a family hookup than I would think you can find a way in. That same friend wanted to schedule a trip there for my bachelor party last summer but I think we realized that we would not be able to maintain proper decorum, so we went to a shooting range instead.
I am trying to think of other weird stuff to do that is relatively new in Madison (since I know you come back semi-regularly) but am drawing a blank. Not to say it ain't there... I am just kind of a homebody at the moment and am more thinking about my move away from here than what's actually going on. You could always rent one of the big floating porches from the East Side Supper Club and have a cookout ON lake Monona, but I think that is kind of pricey.
Unless you're going to La Crosse for other reasons, not sure that the huge 6 pack is worth the full drive, even from the Dells it's over an hour to get there. Some nice landscape there, by WI standards, but, uh, the bluffs ain't exactly impressive by Bay Area standards...
