We have an interesting UFO report from a truck driver who was traveling through Colorado in 2010. He was a passenger in a truck which was near the New Castle/Rifle area when something out of the ordinary happened.
A bright, green unknown object was seen descending from the sky. At first he and the driver thought it was probably a comet, but soon realized that was not the case.
Check out the report at Green, Unknown Object Encountered over Colorado, and be sure to add your comments.

Would like to see his drawing of the craft as he remembers it, as well as a more detailed description. He is articulate and appears to have a memory for detail, as well.
