- Today's location was in Silberthal near Bürgel, not far away from the road and easy to find - this has been enough opportunity to have a nice cycling tour
after work and go for the Twister Geohash
with our dragged-along

- Instead of playing the hard-working housewife, I used my day off to beat my own record for my longest bicycle geohash. And reached the point hours before Reinhard did, who went there after work.

- The last gooddamn sunday geohash I'll ever do in "nice weather" and that's "not so far away". I'm so sorry I even dragged someone along. Luckily, we didn't kill each other.
