Every morning my father and I took a brisk walk in the forested hill behind my parent's house.
Our last morning together before his trip there was a dense fog in the whole valley, and we kept climbing higher and higher through the beech-oak forest to get above the fog. The sun was shining by the time we got to the top, the Schwarzenburger Turm. We climbed the tower and had a wonderful view of the surroundings -- you'll have to wait until I get back home and download the pictures to see!
On our way back down the stairs we passed an elderly gentleman and said "Guten Morgen!". We had nearly gotten to the entrance when we heard him yodeling at the top -- an amazing sound with all the echos of the tower's stairwell.
And the Saarland is not anywhere near the Alps -- but the tower worked perfectly!
