Lacknothing and I worked on this puzzle a year ago, got one set of coordinates, but came up empty. We got another set of coordinates shortly after that and it looked like a reasonable place to search so we spent a long time looking. We came up empty handed again. Maybe we have a number off.
Fast forward over a year, and here we are again enjoying the carvings on the house and trying to get some numbers that work. With new coordinates in hand the search begins again and what joy to hear that Marie spies the cache.
Very awesome house, and puzzle. Thanks for bringing us here just for the "brunn" of it. TFTPC
