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 or together with Leidenfrost whenever one is reasonably reachable by bike, train, or bus.

I have visited 1 Globalhash, 42 Geohashes, 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 two, both while I was on vacation abroad.
