We will be in Milwaukee the weekend of May 31-June 2 for a wedding. We are staying at the Hilton City Center. We will be tied up with wedding festivities much of the time, but will probably have a few hours Friday afternoon and Saturday morning to do a little exploring. Any suggestions as to what we might want to check out in that general vicinity? We will have a car, but only short jaunts would work with our time frame. Thanks in advance.
