I have to say that my little boy and I found it at one of the least scenic or tranquil locations I have seen in my caching time: under a dirty bridge with lots of pedestrian muggle traffic overhead, but at least there was flowing water and I hear Feng Shui is big on that. Also I have to admit that the park around the bridge is probably the most scenic place in Hannover.
Gonna take the little fellow with me and find it somewhere with a good view.
