Question in series 4 episode 1 Russel is sitting in a bug out then finds the skin on the branch well when he hears a noise in the dugout he turns his head right ? What is the shadow figure on the left hand side the shows does not seem to spot this also when Ronnie is on his own at the end inside his rope bells what is the distortion to his right and then the bush moves still nothing said by the film crew ??? The best bigfoot hunt ever we were glued to the box in all 4 series can't wait for the 5th series.
