There are tons of castles to see, Ktown(keiserslautern) is somewhat americanized, if you have access to the bases, go to Volgoway (its how its pronounced, can remember how to spell it) the amry base in Ktown, got to PX best deal on Lead Crystal if ya like that.
Take the rhine rive boat cruise, it is great!
Octeberfest is a must!
Go to McDonalds so you can buy a McBeer, yes they sell them, you will have a story about it years from now.
Hookers(before wife comes) will sit in their car with dome light on if your into that.
Ther is of course the Concentration camps to see.
You will also be pretty close to Paris. I think it was a few hours via A6 autobahn, well that may not be the right number.
Traveling via the autobahn, remember all destinations are done by cities, like there are no North, South, its Munich, Ktown, etc. Alos if ya see a dude with a lil white lolipop looking thing and he points to you, pull over its the cops. Also tickets are also given via remote radar units. - Speed is in Klicks, not MPH the conversion is 100 = 60, that is 100 KPH = 60 MPH.
Germany is great, I loved it, I spent a few years over and got out of the military and stayed for a bit after, you will love it.
SPeaking- even if ya hack it up, try to speak it, once you attemp it, the Germans will speak english, remember they ALL speak English so watch what you say.
If you out lat and see a "Snhell Imbus", its a small roadside thing, they sell beer and food, I recommend the curry wurst and a beer, fantaastic!
Tray to bring home as much beer as you can!
Take the time to go to Berlin, see and get a piece of the wall, there is a bar in town that has hundreds of beers. Tons to see in that town.
A RatHouse is they local pub, they are cool.
All the boarders are open so you can travel to other countries, no are to far really.
