Our favourite cache is Sösebub's "Lost Place: Rommelkaserne" (GC1XWV5), it was one of those typically rainy love-it-or-hate-it days, when you feel like there is only a good cache that could improve your mood. Some friends and I, we finally decided to do that multi. First instruction was to find the "P". We struggled until we finally realised the simplicity of the task. The second cache we basically ignored, however, we managed to find it in the end. To our misfortune we ended up in a field having read the wrong coordinates far away from civilisation. Nonetheless, the little tool we were given and the idea of a "canon" as a final cache were both adorable.
Thanks for the TB.
