Fantastic! Post a trip report afterwards.
8/24 mystery solved, per wikipedia:
As of June 2007, the official RATM website is down. The website www.ratm82407.com was launched in June 2007, featuring two countdowns: one ending on June 11, 2007, the day when the website's purpose will be revealed, and the other ending on August 24, 2007.[35] The website's connection to the band is unknown. The website is registered to Live Nation Worldwide, Inc. Live Nation owns Alpine Valley Music Theatre, in East Troy Wisconsin. By turning your PC clock forward to June 11 the website reveals that RATM will be playing a show there when the second countdown ends on August 24, 2007.
