Every year, the Deutsche Weinstraße (Wissembourg in the south to Bockenheim in the north, 85 km) kicks off the cars for one day to let the people get out and walk, ride and roll through some of the country's more spectacular scenery while sampling the region's finest product: Wine.
This year it's Sunday, August 31st.
More about the Deutsche Weinstraße here and here.
And info on Bike Day (Erlebnistag Deutsche Weinstraße) here.
I can't recommend it enough. We'll be starting somewhere north, riding south through wine-making mainstays such as Bad Dürkheim and Deidesheim before wrapping it up in Neustadt an der Weinstraße. Neustadt is well-connected to Mannheim, Heidelberg, Kaiserslautern, Karlsruhe, Speyer, Bad Dürkheim and Landau, so if you're anywhere around these parts, you should really get out and do this.
If anyone wants to join us, please let me know.
(I will post this in the BW section as well.)
