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.

So far, I have visited 1 Globalhash, 79 Geohashes (71 successful), and 47 Retrohashes. In September 2018, I made a commitment to reach every hash within the administrative borders of my hometown or any of the 8 surrounding townships, an area of 269.8 km². So far, I only missed three, all while I was on vacation abroad, and got 34.
