This was my main reason for detouring up this way on the way to Kiel.
Left Madison solo at 4am this morning hoping to grab some caches I needed for challenges before meeting up to tackle the firefighter series. This one filled in a spot for Trekkin' and birdin's cheesy well-rounded cacher, so I spent several long nights banging my head before the solve was finally in hand. Pulled into the area just after 6am and under cover of darkness made my way to GZ, luckily I stumbled upon the container on my first attempt regardless of the snow and dark. Fun puzzle, thanks for the brain-bender!
