The first 4/5 k of my walk were very boring, but then I got to walk this area which was gorgeous. The last 3 km were wet! I went home by car, took of my very wet pants, stretched and took a shower. Total of 16.3 k today.

@Storm: the tower had 2 lines on it: the first line was the hight of the surrounding dikes, the second one the water level of the 1953 flood.
