Another fairly old stone can be seen at
http://www.natur.cuni.cz/~kuhn/gallery2.html (Old boundary
stone from 1672 north of Polesà near Rynoltice). I've looked up the location and although I can't be
sure, it may be a working one on the czde border (near the German village of Luftkurort
Lueckendorf). So it's probably not a gold medal candidate, but nevertheless a nice one.
Wonder what FAB stands for... International rescue?
