Evidence of human manipulation

Explanation:

Many similar cases like Paulding Light were springing up all over the USA at the time of the investigation's heyday.

The unexplained light soon lost its charm as many other places were found out with mere headlights and flashlights.

However, It has never been proved that there was in fact human manipulation involved in this case itself, disconnected from all other places.

Travelers on Highway 66 today can easily experience this past through the many motels, gas stations, cafés, trading posts, and roadbeds that remain along the highway.

It was sold as "the shortest, best, and most scenic route from Chicago through St. Louis to Los Angeles."

Business owners in small and large towns along the highway looked to Route 66 as an opportunity for attracting new customers to their often rural and isolated communities.
