Hi Bronson,
a few hints for finding a dojo in Germany besides aikiweb's search engine.
A good address (though in German) is
www.aikido.de with links to many dojos and all organizations' websites, who also maintain their own dojo directories.
On Maps for Germany:
www.yahoo.de -> fin the link to "Routenplaner"
and type in your City or Zip code under "Stadt", then it works like any other.
Those two I found with no effort on the web, others may be there also:
Kaiserslautern (10 miles)-
www.aikido-kl.de/aikihome.html
Saarbruecken (35 miles)-
www.sakura-dojo.de
Good luck!
Olaf
