The Wandering Foursome

I went for a hike in the hills and in the Glan valley around Nanzdietschweiler. Wanted to go exploring a little path I discovered last year when I was frequently visiting the Kneipp basin there.
It was an uphill and downhill hike which I'm not used to, but I was feeling good and had fun - seems like the holiday feeling is finally kicking in.
I spent an hour on this bench, sponsored by the "Wandering Foursome" and put up by the PWV (Pfälzerwald Verein Nanzdietschweiler). 
Already tried to find one of the Wandering Foursome on Facebook, no luck so far. Any other ideas?
