cli0202firetrain1 -- Gene Schaller, middle, is assisted through a hole in the wall, part of an obstacle course marked of cramped spaces and low visibility by Brian Collins, left, as Eric Kallem looks on during Clive Fire Department training in a vacated building on 86th Street on Wednesday, January 30th. Kallem, who helped to construct the course, said that the training was helpful in providing firefighters with realistic situations in a safe environment. DANIEL SATO/THE REGISTER (The building was across from Krispy Kreme on 86th Street and Alice Avenue in between what looked to be a bar and a lawnmower or engine shop.)
