Actually, (off the top of my head) I have somewhere in my files an interesting 1968 case from the SLV that features a two-car convoy traveling late at night north on State Highway 285, just south of Villa Grove, CO stopping upon seeing a lit up disc coming down and hovering a couple of hundred yards east of the highway. One of the passengers, a U of CO student, jumped out of the car, climbed over the barbwire fence and began to approach the object that was hovering a few feet above the ground. As he got within a hundred feet, or so, he was hit by a beam of light that appeared to the others in the car to knock him down. The object took off and the others raced over the fence to see if he was alright. He had been knocked out cold and (if memory serves me correct) it took some time for him to regain consciousness and his senses. He wasn't abducted, but pretty messed up. I thought I included the case in my first book, but a quick look through didn't produce it. I'll do more checking, but it was investigated at the time by Don Richmond from APRO, and I think, Richard Siguismond. Again, this is all from memory, but the case was apparently the real deal.The Walton case was actually quite unlike most abductions, which usually don't involve witnesses other than the abductee(s); nor does an abductee initiate an encounter i.e. run toward a UFO, or get zapped.
