I managed to reach the city park. My friend was waiting for me there. Damn he has prepared himself well and he gives me some food, water and clean clothes. I connected my phone to his powerbank to charge it. We discuss the plan and the situation. It is about an 8 kilometer walk to the forest. He indicates that he knows a relatively safe route, but that we have to pass a military barrier. To pass it we have to go through the sewers.. Wish us luck.
