austrias nice too... but black forest around the bodensee is gorgeous...
one of europes longest tunnels down there... now that with a non standard can is on my list of things to do sometime...
FuBen [read as foosen] is close to koningschlossen which is where the chitty chitty bang bang castles are. The food in that part of germany is some of the best you will ever eat.
