Sergeant John G. Totzke, 22, from Lees Summit, Mo., is next in line as he waits to buy a CD and magazine at the grand opening of Camp Taqaddum's main exchange July 1, 2006. The exchange services here moved their store from a wooden building to a much larger structure to provide their customers with a more open area to shop that stays cooler than the previous location. Service members go to the PX to buy goods ranging from basic hygiene equipment such as toothpaste and razors to luxury items like the latest video game magazine or favorite soft drink; the latter category crucial to Marines fighting in the forefront of Operation Iraqi Freedom.Photo by: Sgt.
