I saw a couple of bike races in Europe. Above is the Liege-Bastogne-Liege bike race, in Belgium, and below is the Rund um den Heninger Turm race near Frankfurt.
One day I drove along the Rhein for a while and ended up going in this castle (abov), called Burg Rheinfels in St. Goarhausen. This is the view (below) from the to of Burg Rheinfels.
