I decided to carry that bug outside Prague to a cache belonging to one of the Czech most famous castles - see photos. Perhaps some american or japan tourist with GPS finds it here :-) Well, more probably someone takes it back to Prague, but in this case you at least got some photos of the castle, which was built in 14th century as a safe for czech coronation jeweleries. The foggy photo was taken today from the cache, I also add two photos taken few weeks ago from the opposite side.
