GPS is amazing. I cannot imagine how people survived the old fashioned way. The only note I will add is that Germany seems to have a lot of towns in the same general area with the same name.
The guidebook for Munich and the Bavarian Alps says that to get to Chiemsee, you must go to Stock. Of course, we went to three Stocks. The last one being the correct one. It was all good. At least it stopped raining by the time we arrived. This is Henry checking out sheep in the second town called Stock.
