Awesome and hilarious post.
Sadly I highly doubt there are any large land animals we haven't identified yet. I mean let's be real, the majority of people now have camera phones. So it's not like it's 1905 when someone spots Lochness but can't get a picture of it.
Also, there are trail cams all over the place in these remote locations. Especially locations where the Cryptids are supposed to be located, and nothing has turned up in over a decade of non stop use.
More than finding one of these non existent animals, I would love for a Tazmanian Tiger to turn up after over 80 years without a legit sighting. I also highly doubt this would happen, but it would shock the scientific community for sure!
