We were stationed in Germany for 3 years.
The good thing is that you can take your pet. Our dog was with us the whole 3 years. The have to have an international shot record though.
You have to make sure your car is very clean when you ship it. Also make sure the tires have enough tread because it will be inspected. Also you can not have anything in your trunk except for your jack.
You have to have a first aid kit and warning triangle in your car when you pick it up in Germany.
If you have an SUV you might want to think about either trading it in for a smaller car. Parking is hell in Germany. We had an Explorer and used to have the hardest time parking it. Most of the parking is parallel and it is hard to do when the space only is about the size of an economy car. Your other option is to leave your car at home and buying a clunker while you are there to use for 3 years. Alot of families do that too. There is always someone PCSing that wants to get rid of a car for cheap.
The good is that Germany is a breathtakingly beautiful country and there is lots to see on the weekends.
The bad is that you can rarely "escape" the Army. You live it 24 hours a day. At least stateside, you can kinda "get away" for a little while.
You will get SICK of the PX. All of the stores on the economy close early and most are closed on weekends. If you are not into the club seen, the PX will pretty much be all there is to do on the weekends unless you want to drive and sightsee, but that gets old too. So, you will do ALOT of shopping at the PX and commissary. To get a change of scenery, we found ourselves driving to different PX's all over Germany just to shop someplace differnet. A big tip would be, if you see something you want, you have to buy it then or it WILL NOT be there when you get back.
Learn at least a little German. You will need to know the street signs at the very minimum in order to get your license.
Buy a bike, you will understand why when you get there.
Housing is very small there, even if you live on base. I would recommend trying to live off base so you can have a little more freedom.
It can snow anywhere from October until April. I remember one year it snowed on Easter. I have cute pictures of my kids Easter Egg hunting in the snow.
The food is soooo good! There is a bakery on every corner and you can get fresh bread and desserts all the time. The Winter fests are the best for getting crafts and traditional items too.
I loved our experience though, and I would go back in a minute, but I would not go back as an Army family.
If you have anymore questions, please ask!
