We head to eastern France to discover the "blue line" of the Vosges mountains, running along the pre-1918 Franco-German border. It was named by the 19th century statesman Jules Ferry who separated the Vosges from the annexed Alsace-Lorraine region. The ridge can be seen much more clearly from the air. We meet some lucky tourists taking a balloon ride over the peaks. The Vosges mountains offer a lot of winterholiday possibilities with skiing. The local farm inns with their local gastronomy are the best places to meet the locals. The Vosges mountains were also the scene of heavy fighting during World War I and local associations are keeping the memory of the fallen soldiers alive.
