This slipped under the radar on the Internet but recently has set it on fire. Is it real or fake? Whatever it is it certainly appears behemoth!!
...For those who have a passing interest in the subject matter or cryptozoology I'd really recommend the Astonishing Legends Podcast, they have a few episodes on the Patterson Gimlin film aka 'Patty' where they examine in very detail all the details to the story.
That film has probably been viewed more than the infamous Zapruder film of the JFK assassination. Despite as such, few if any people have changed their opinion. It's still highly controversial.
