Despite the freezing cold (-15 ° C) I went skiing again this morning.
The "80 km" sign is part of the "Fernskiwanderweg Schonach-Belchen", a 100-km-tour through the Black Forest which is marked by the orange symbol (to be seen in the picture, too). I have never done all of the 100 kms - just parts of it.
That's the only picture I took - it was too cold to stop more...
