This Geohash is located next to a carport on Bauschheimer Weg in Mainz-Laubenheim.
Five graticules in 24 hours, expedition 4/5
After visiting 2022-06-11 50 7 in Friedrichssegen, I walked back to the Friedrichssegen station. I picked a train route that differed from the original plan, going to Bad Ems first and then back to Niederlahnstein, and then via Wiesbaden and Mainz Römisches Theater to Mainz-Laubenheim.
From there, I walked the rest of the distance. The Geohash was right next to a carport, and I could locate the coordinates fairly easy.
Afterwards, I left for 2022-06-12 49 9 in the Waldaschaffer Forest, but did not get very far that night. I ended up sleeping in a park, 846 meters from the Geohash. However, since I wasn't there at midnight and stayed only four hours, I did not fulfil the letter of the camping geohash achievement, though I like to think it was in the intended spirit.
