 The graticule
The Gliwice graticule is located at 50, 18. It contains several smaller cities (including Zabrze, Bytom, Chorzów, Rybnik, Żory and Tarnowskie Góry) and an eastern part of a bigger one -- Katowice. South-eastern part of the graticule is quite urban, the rest is mostly rural and includes a lot of forest. Meeting in the middle of a forest may be quite exciting.
