Yes. He is an Alien, visiting from another dimension. Local Legend says that if you can touch his long white beard, you get one free wish. No one has been able to keep up with him. If you watch him carefully when he walks, you will see that he has the ability to levitate over crosswalks, and sidewalk obstructions. His plaid Shirt, Khaki pants, and hat are all part of his Uniform, required by his Military, in the other dimension. he also has a holographic image projector, that he uses to project himseldf all over the city. That explains why you might se him on different parts of town, going in different directions at almost the same time. He was also a student of Dr. Steven Hawking, who shared with him the secrets of Black Holes. Oak Ridge has so much residual excess energy from the Manhattan Project, that Black holes are plentiful, and make his travel between dimensions very easy.

On the other hand, someone in another recent thread mentioned microdot. I remember those times ... and I gotta wonder if LSD's making a comeback.
