Finally I found the time - it's January 28th when I write this - to work on my backlogged geocaching administration, and am now able to log this trackable. I discovered it November 8th 2022 at 18:14, in 127 - Wegwijs met Wiskunde - 'de laatste', the final cache of the 'Wegwijs met Wiskunde geoart' near Hengelo Gld, the Netherlands.
