During a short tea break, Jürgen draws our attention to the signs that are displayed at regular intervals on the trees. As he has guided us so purposefully through the forest, I hadn't noticed them before - now I see them everywhere.
"There are over 23,000 kilometres of hiking trails in the Black Forest," our guide tells us. "All the markers have a name," he explains, "so that the rescue teams know immediately where to look for anyone who requests help." "So, you could also go hiking without a guide and without worrying?" Felix asks. "Of course," Jürgen nods, "but it's more fun with us. Besides, you only see what you know, and we know quite a lot."
