We have left the Ukraine behind and made a discovery in Russia. Racing tractors has become a real sports holiday for agricultural workers in the Rostov region - the centre for tractor sports. The "Bison-Track-Show" is now world famous - what a great idea! . Tempted though we were (imagine the miles we could cover by tractor!) we resisted the easy option and continued our Hike or Bike onwards through the Forest-Steepe and across the border into Kazakhstan.
