In the small town of Springer, Oklahoma (near Ardmore) lies an ordinary hill with a strange phenomena.
If you put your vehicle in neutral at the bottom of the hill, it will suddenly appear to defy gravity as it rolls backward, uphill.
Many theories exist about why things roll uphill instead of downhill. Whether caused by ghosts, a magnetic force, alien contact or an optical illusion, this is something you have to see for yourself.
