B500 - Schwarzwald

They say "The best German Road to ride a motorbike"

Did it in one day from Waldshut-Tiengen till Baden Baden.
What to say, the road is really to be ridden once in a life but definitively I would not call it the "The best German Road to ride a motorbike".
The road in some paces is excellent but mainly is repaired with liquid asphalt and has "snakes" therefore often slippery but, it worth to be ridden!
