Have driven from Bastogne then Houffalize then over to La Glazie (Town next to Stoumont where Pieper and his detachment from the 6th SS was stopped) then over to Malmady, Houffalize & Baugnez (Malmedy massacre at that crossroads) the over to Elsenborn Ridge where the 6th SS was squeezed south and stopped. Course didn't really have time to cover everything but it was an awesome run. Stay one night in Monchau (Germany) very small quaint town.
If you have never stood by a Tiger II (King) it will blow you away at its size (the commanders coupla is about 9' off the ground and it's about 12' wide). Every little town has a tank, monument or something commemorating the Allies.
My great uncle was in one of the units that reliever Bastogne and brought back numerous bayonets, knifes, medals and two of the giant red banners with the black swastika in a circular white field), still have all of that along with pictures of his run from Vianden, Bastogne and then into Germany. He served aboard a quad .50 AA half track, but said they used that setup most of the time against German infantry. Am in the process of scanning all his pictures in right now.
I've read numerous books on The Battle of The Bulge and highly suggest "A Time For Trumpets," as one of the best.
If you ever find yourself with time, rent a car and see as much of the area as you can. Your also within driving distance of seeing Ft Eben Emael, fascinating place. You'll also be treated very well by the Belgiums and the countryside is beautiful.
