RE: Germany
I spent seven years in Northern Europe 40 years ago. I finally went back for a visit this spring. Things have changed a bit. I still would give my left you know what for that 4 year tour you have.
As for Korea I have never been there but I have a friend that spent a year on the front lines over there. I don't think I would like it.
As for Kansas, I grew up in Nebraska. Its a good place to be from - far from.
