I really enjoyed reading your post so much, I also made a plan a similar journey 5-6 days ago. A journey from Istanbul to Ukraine, then to Russia and finally to Mongolia.The journey will about a month and during this time i will have the chance to visit many places and of course will be alone and take time for myself. As someone who goes on long trips and loves it, really understand you very well.I know you enjoyed it extremly and congratulate you. See you on your next trip, take care! drive safe!
