In Birkholz (Brandenburg), just behind Berlin's southern border.



Relet will be there around noon, since he still longs to test that new electric car, and the station is only open 10-15. Parking near Nachtbucht, taking a short stroll (he is not allowed to drive the car outside the city borders), and possibly looking for a few caches later on.

Looks like a hash collision, finally!

relet and davidc[edit]

We met at the Hauptbahnhof (main station) at 10:30 where relet rented one of the new electric Minis. The hash point was just south of Berlin, and the car wasn't allowed outside the city, so after an accidental overshooting of the city limits, we backed up and parked in Lichtenrade and walked the remaining 2km through forest and rape fields.

We visited geocache GCHAHV Balladencache on the way and passed right by another but decided to head directly to the hashpoint to keep our appointment.

At 12:00 we arrived and had a brief argument over the exact hash point - relet was using pure GPS and davidc was also using the overhead satellite map - when Trurl turned up on his bicycle and added a third GPS to the argument. Compromising on one side of the track, the obligatory silly grin photo was taken.

davidc then headed over to the other side of the field to the geocache GC15NT8 An den Mahlower Fishteichen. This earned us the Hash collision achievement. relet and Trurl stayed behind to take a photo. You can just about make davidc out in the red geohashing shirt across the field, thus proving line of sight for the ribbon. Further proof is shown on this point to point map. The logbook was duly signed and a red herring geocoin swiped.

Trurl headed back home, so davidc and relet picked up another geocache, GC1TB41 Mahlower See, before ploughing into the forest with great abandon, attempting to find a direct route back to the car. Bravado gave way however to caution when a field of dense nettles forced the shorts-wearing davidc to stop. Returning to a field we found a better route, picked up GCH9NW Fuschbau and returned to the car.

Back at Hauptbahnhof, we visited GCZCQ7 Berlin's Bahnhof before parting ways. davidc remained to pick up antihistamine cream for all his bites and stings, and then did himself proud finding GCWEFD Berlin-Hauptbahnhof in broad daylight with thousands of people around, deftly timing his leap over a fence to avoid being seen by the many stationed police, and dropping down and across under a bridge.


Jerrome arrived at the spot somewhat late, about 1620. Using a GPS device intended for a bicycle on a motorbike prooved to be a little more difficult than previously thought. Almost lost my hat, too. Found the markers left behind by relet and davidc.
