The Sheep locked itself up on the rock. I thought it would be lost without help. In fact I was lost too! I was loosing against time and darkening. Darkness was comming in faster than I ever could get out of the forest. I walked already at least 7 hours and my feet were hurting...I had also a dilemma: following the river on an unknown path in complete darkness hoping it would lead me to my car, or getting out the wood and add a few hours more walking along the road. The thought of sleeping outside in that cold weather let me choose the latter.
Back in civilisation, I asked a friendly couple to call the forester to free the sheep.
A few hundred meters further, a kind man stopped his car and drove me to mine.
A few weeks later I returned to the rock and the sheep was gone. All ended well I think.
