One evening, driving our car on the E17, we came out of a tunnel near Antwerp, Belgium, and were suddenly confronted with this… sky? As I was the passenger, I managed to take a few pictures trough the front window. We felt like driving under an upside see of waves. It had a beautiful dampened light and the world suddenly looked very different. A sense of unknown danger was also present. We had no rain or storm and made it safely home. Other parts of the country that evening were not that lucky.
