About the "end of the fence", the text in the booklet says (roughly 
translated):
    "From Prex (the town in the map south of the tripoint) there is no 
direction sign pointing to the tripoint.  It is the tripoint where 
Bavaria, Saxony and Bohemia formerly met [explaining the "S" and the 
"DB" on the white markers].  From the road to Hinterprex, a dead end 
forks off to the left, ending at a parking lot.  From there, a 50 
meter long path leads past a soldier's grave in a low, wet area that 
comprises the source of the brooks that develop into the Regnitz 
river.  The meeting of the borderlines, marked since at leats 1844 as 
can be seen on the one stone, is on the transition point marked by the 
red-white and the blue-white fence [horizontally, in back of the 
rght hand border stone, but not seen well in the scanned photo].  At 
this quite, remote village, on this inaccessible point, and under 
rules relating to the protection of nature live river pearl mussels.  
There is almost no information about the history or the current 
situation relating to the borders.  This southernmost point on the 
East German - West German border is utterly unspectacular.  The border 
fortifications are set back from this site and are hardly visible to 
the visitor."  
The photo, to answer someeone else's question, had to have been taken 
prior to 1984, when I got the booklet.
