Last weekend I was cycling along some of the marked cycle routes and I'm almost sure that one of the signs on the marked route shows the wrong direction. While following FO5/FO12 I arrived at the following crossing coming from east:

osm.org/?mlat=49.6555&mlon=11.1834&zoom=14&layers=00B0FTF

At this crossing the sign for FO5/FO12 guided me towards north-east. However, at the next crossing, there was no sign anymore. So I turned and headed for the small village Pommer, where I found a sign for FO5/FO12 again. So I believe that the road north-east of that crossing is not part of FO5 and that some jokesters have changed the direction of one of the signs at that crossing.

Could you please double-check the sign and the cycle route in case you're eventually close to that crossing.
