Marko Yurachek, Adventure Guide, Special Guest

Marko spends his summers in Alaska as an Adventure Guide. Either a bear ate his cell phone on one of his Grizzly Safaris or he has spent the past several weeks without reception (which is a wonderful thing) so as the course director, I will write his bio. I am sure Marko would be able to add tons of other super cool facts about his adventures. We cross paths at many regional Wild Med conferences where Marko teaches primitive skills. His skills are numerous but include climbing, SAR, any outdoor or primitive skill, navigation and leading Adventure Expeditions. His best trait is his personality. Friendly, personable, humble and a great story teller, I highly suggest you spend some quality campfire time with Marko. He has also been the personal primitive skills trainer for one of the "Naked & Afraid" contestants (who kicked butt on her episode by the way).
