Crayfish are being prepared in front of a mobile sauna that is mounted on a four-wheel drive truck in a forest in Barnaul in the Altai region April 5, 2008. A local craftsman installed the Russian sauna, or banya, in the cabin of a four wheel-drive personnel carrier and said the rugged army vehicle can master almost any terrain.
