On his blog site "The Davis Report" MK Davis claims to have stuck his hand into bigfoot mucus while examining a track find. This exposure to the mucus made him extremely ill, to the point that antibiotics wouldn't even work against it.
These tracks were found in Bigfoot Country in Northern California. What distinguishes these tracks is that there are secretions in one of the tracks that appear to be mucous. If the Bigfoot was sick then this mucous was blown out into the track. The person who’s hand is picking out the leaf litter is me. I wore no gloves and in my excitement I put my hand right into the mucous. By the time I got home I was already sick. I was violently sick for over two weeks and antibiotics had no effect on the condition whatsoever. Look for the mucous in this video.
