Never been that far south YET !!!
One piece of advice I can give you is..
DO NOT FILTER through traffic...
TOTALLY illegal in Germany... If they see you doing it, they will lock you up & throw away the key...
If you get pulled byt the Polizie, be very, very, very polite, and helpful, and the chances are they will let you off any little misdemeaners. If you arent, then its a long walk home when they have confiscated your bike...
Just remember also, that not all Autobahns are de restricted, and speed limits DO apply on a lot of sections...
Enjoy Germany, it is a wonderful country to ride in... The roads are almost billiard table smooth, and they are deceptively fast when having fun... Also the germans bikers wave at every bike they pass (its easy being on the other side of the road) Very friendly...
Jan & I love the place... Off to the german blackbird bash at Alsfeld at the end of May.
Enjoy.
