Tennessee "The Invisible State"

In 1895, the diabolical Professor Pandemonium flew his giant airship over the Volunteer State and used his Light Diffusement Cannon to render the entire state invisible, with the intent of then ransoming Tennessee for millions of dollars. Imagine his surprise when the weapon exploded a few minutes later and took the airship and all aboard with it.

This left Tennessee in a hell of a fix, which science and even Science! Have not been able correct. Today, it's 2018 and if you go to most of the Tennessee border, you can only see what looks like a humongous earthen pit 50 feet deep. If you go to the spots where roads or rail lines enter the state, you'll find the 2 mile long tunnels that where constructed in 1897 to let folks go in and out of the state without freaking out.

You see, inside the Tennessee border, everything is perfectly visible. If something or somebody leaves Tennessee, they become visible. Thus, the whole invisibility thing has only a minimal effect on day to day life. But without those tunnels, hoo boy, would there be traffic jams.

Note: The invisibility effect only works on humans. Animals and cameras can see Tennessee just fine.
