Don't know if this is a good idea or not, but if you know of a road that really shouldn't be traversed, and you think other LD riders should know about it - why not highlight it and put it on this thread.
Tell us WHY it is bad, as your reasons may make others immune - i.e. it's 20kms of rough dirt! <------- doesn't worry a Veradero rider. Also - put the road name up first for quick recognition.
One that comes to mind for me is the Killarney-Woodenbong stretch.
