Following my investigation of Kerkrade-Herzogenrath I drove a short way south to where the German town of Aachen and the Dutch town of Vaals meet at the international border. After finding a geocache (Westwall Bunkercache "MG-Schild Wachtelkopf") near an old German bunker which was right across the road from the DENL border (just north of Vaals, on Senserbachweg), I drove through the outskirts of Aachen and the town of Vaals and then on to the BEDENL tripoint. Here is some video of parts of that trip.
Again, I hope this gives you a bit of a flavour of this part of my trip.

Next stop - a few places on the Vennbahn and the BEDE border area as I head south towards Luxembourg.
