The outdoors, free music, good beer, good friends. Wisconsin can be lovely when they aren't raving football lunatics. :) Nice amount of tables and space, right on the lake.
Rec: If you see abandoned pitchers, take them! You get $1 for each that you return. I saw some girl with like 11 of them. :) Don't forget to return yours, too.

Only Union members can buy beer. Seriously?
