re: What Does the OT Know About Grafenwohr, Germany, or Bavaria in General?

Unless your other options are Vicenza, Italy or some other decent OCONUS duty station you'd be a fool not to take it. You will never have the ability to travel and experience European culture again (unless you find civilian work there later) like if you were stationed there.

As long as you don't hang out on post and complain about how there's nothing to do you should have a blast over there. Good luck, Toujours Pret!
