10-Feb-2001 -- 53N 18E is located 15 km south of Bydgoszcz, not far away from Brzoza. That was my first confluence, therefore getting there through the forest took me about an hour! Finally, on some other forest duct the GPS device showed the confluence was close ahead. Having left the car we walked a couple of steps forward and there it was -- the display showed zero values for the spot. The first confluence completed. Now we only needed to confirm the spot so my son and myself took some pictures and in a thoroughly dirty car headed back home.
