From the Phantom Regiment Web site:

The Phantom Regiment offices were a part of the casualties of the storm that hit Rockford, Ill. on Labor Day. The storm caused flooding throughout the city and knocked power out to at least 5,000 homes and businesses. Fortunately no one was at the offices at the time of the flooding. The Regiment offices are located on the basement floor of the Burpee Center at Rockford College. The four to five inches of water brought by the storm caused a drainage system to fail.
