I love this show too. I saw the episode where Josh and his crew went into a forest in the Soviet Union (I think).
They talked to villagers about the forest and were warned to stay out; if they went in they would not come out again. They made their way to a large clearing within the forest and set up camp just outside it. One by one the crew would sit on a chair in the middle of it. THEN...the camera caught one of the crew sitting in the chair and all of a sudden it looked like something grabbed the man by the scruf of his neck and yanked him off of the chair backwards...he was found about twenty yards away from the chair lying on the ground in shock!!
DAMN, that scared the chit outta me!!!
