The men on top of the fire truck told officers they were members of the Sinful Saints Band, which is based out of Crystal Lake, police said.

The band had just participated in a Founders’ Day Parade in Lake Forest and had been riding on the back of the fire truck.

Officers learned that at the end of the parade, the truck’s driver made a wrong turn and drove north on Green Bay Road towards Wisconsin instead of returning to the disassembly point for the parade.

The band member passengers could not get the driver’s attention to alert him that he was going in the wrong direction and that they were still on top of the fire truck.

After the traffic stop, the band members were transported to the Pleasant Prairie Police Department.
