Found details of some of the ceremonies here: http://www.visitbelgium.com/pdf%20files/60...he%20bulges.pdf
Why don't you try this site? http://www.amba.lu/ That gives the full programme of festivities..... Will do some re-enactment in the Bulge in december, there is a meeting near La Roche, where they go in convoy with military vehicles to some of the places where the festivies are, so that will be nice! :P
