Been to London for a weekend as my birthday present. So we explored the city while caching, went caching while exploring the city. Had a wonderful weekend.
We solved this mystery before going to London, because we wanted to get the PI Day souvenir double. Thanks to the geochecker link, we were able to prove our solution before going to GZ. Very funny hiding which we at first sight did not identify as such.
thank you for taking us here and greetinx from Hamburg
