I am a traveler, snowmobile, snowmobile school instructor, photographer, youtuber. I ride a snowmobile in the mountains of the Kuznetsk Alatau (Priiskovy, Khakassia, Russia). In the snowmobile season 2018/2019, I skated 106 days on a mountain snowmobile in the mountains! In the offseason I travel and do outdoor activities.
