This is the tunnel from Yvoir. First I biked around the mountain, then I walked into the tunnel. While I was standing here in the darkness, a group of scouts passed me. The front end of te group did not even notice me, untill some girls in the back of the group started screaming in Dutch. One of the leaders of the group asked me if I was part of the group. I answered them in French I did not understand them and walked away.
