If you're headed form Bernkastle to Aachen on the Wed, I'm assuming you'll be heading up the B258 at some point. I'll keep an eye out for you guys as I'm touring the Eiffel region on the bikes with a friend that week and as we're staying not far form the 'ring we may well cross paths.
Have a great trip all. I hope to be able to join you one year soon.
