"Feeling I was in no danger, I stepped boldly out on the trail. The giant luminous humanoid stopped, and turned around. Wow, to lock eyes with something like that.

"It stood there for several seconds, looking at me while I looked at it. Long enough for me to get a pretty good idea it was NOT homo sapiens or Sasquatch. I don't know what the hell it was. It was maybe 7 or 8 feet tall, with grayish or greenish gray skin. No hair or fur."
