I would have to say yes I believe that the creature may be real.
I spend a great deal of time out of doors. I have seen things that people say could not exist.
For instance, while on my way to Alaska from Tennessee I saw a very large bird. This happened in South Dakota near Sturgis.
This bird was so big that when it landed on a rock outcropping it looked as tall as a horse. I thought it might have been a Condor at first however, after doing some deeper research the heads of the two did not match up. The Condor has no feathers around it head and neck area.
This bird had black feathers covering it entire head and neck.
I saw it at a distance of only about 10 feet. I had a very close look at this critter.
After seeing this I will concede that things do exist that science has not accounted for.
