25 / m / 53,9

I’m a physics student and geohasher from the 53 9 and 53 10 graticules. I (re)discovered Geohashing in May 2018 and will mostly hash alone whenever one is reasonably reachable by bike or train. Munroe number: 6.

In December 2022, I had visited 160 geohashes (143 successful), 1 Globalhash, and many retrohashes. In September 2018, I made a commitment to attempt to reach every hash within the administrative borders of my hometown or any of the eight surrounding townships, an area of 269.8 km². So far, I only missed six (five while I was on vacation abroad and one while I was in hospital), and got 61.
