A cache hidden in Bonn woods, named after the city of Bonn in Germany.
If you arrive from the trailhead, you walk on the trail for about 50-100 meters and GZ should be on your right, between the trail and the fence, see photo.
Look for the cypress tree.
Better to come during the day, not when it is dark.
I hope this one lasts. Please put it back the way you found it - the top of cache is supposed to be visible, yet the rest of it is held good enough at its place. Hopefully muggles don't sit around here at GZ, but even if so, they may not notice the cache...
