Bulge '44 Map: Why no Trails?

[FM WarB]

You know enough about the Bulge to know it was 4th Armored doing the Bastogne relief effort, Josey.
My Mis type (It is the 4th in my scenario).
Isn't the Bulge a popular enough wargaming topic that an effort to get the map right would be appreciated?
I wish I had a map editor that could do the trick.
