One thing I don't think I've documented on my blog about Germany is the concept of pay bathrooms. All of the gas stations off of the autobahn have bathrooms about like these here where you have to pay 0.75 Euro's to use the facility. The first time I encounter these I was on the way down to Austria a few months back and couldn't figure it out at first. As far as I can tell Germany seems to be the only European country that has these. It's something to keep in mind if your ever over here, always have change for the bathroom in Germany.
