Over the years I have captured video of a gray colored Sasquatch in the same general area of the Great Smokey Mountains National Park. I have at least 3 captures, 2009, 2011, 2013.
I am in the midst of my reviewing hundreds of hours of archived footage that I have never looked at before. I found the 2011 occurrence of this gray Sasquatch just recently. The camera I was using was not a HD camera, but the images are decent.
Below is a comparison of the three captures over the years.
The 2013 capture was made with a HD camera. The details are much better. Below is the video of the capture.
