I am in Germany also and I love it! There are a few people with Jeeps here. I no longer have mine, though. It seems like people have found a place to at least get their Jeep dirty, but I can't forsee there being any major off roading here like you can get in the states (Moab, Rausch, that kind of thing). I don't know about surrounding countries, though. The Germans seem more into preserving the nature, economic cars, smaller vehicles, etc. Not to mention oil and petrol being expensive for them. However, we do have mud races here and those can be a near event to attend.
Next time I run into someone with a Jeep on base I'll ask if they've found any good wheeling anywhere. There are country roads with great scenery though!
