Moving on

We left Amsterdam at around midnight yesterday, and this morning we arrived at Kinderdijk. Our walking tour left the ship at 8:25am, and the guide,  Ad, was excellent,  very humorous. There are 19 windmills,  originally 20, but one was destroyed during the war, 16 are family homes and 3 are museums.  It's a UNESCO World Heritage site.  
Next stop is Cologne.
