Yep. Tail lights are very visible at night, at dawn and twilight. He may have taken precautions on that dinky car, like disconnect the lights, but he doesn't strike me as high functioning on fine motor skills, more of brute force type, and driving without tails would mark his car to police and others. So I'm guessing that he parked, stopped some place around there where the chances of him being seen during those hours were slim, and walked along easy paths, to serve his needs, as they may have been, to where the remains were found. It was stated by a neighbor to Hawes Spencer, if I recall correctly, that 'he knew where to go.' So, would any one who knew him, but may have not of known him to be a rapist and a murder, know where may have liked to go to dry out, around there? If anybody does, hope they tell?
When looking at OLR there is a large curve on each side of the area where the remains were found. Any cars driving on the straight-away from either direction wouldn't see his tail lights at that time. I don't know if that was considered when he chose the spot.
