By the mid 1990's when every other person had either a cam corder, camera or cell phone with camera, I decided that no mysterious object could display itself without good photographs being taken by somebody. Since none have ever surfaced, the answer is obvious.
During my youth I still believed in bad guys and two escaped convicts went on a killing spree near where I lived and I had a gun in my car at all times. Still waiting for that opportunity too! LOL
Sorry, had to make a true story a joke. I see on TV we can now fing Bigfoot with beef jerky!
