This is a historical map that i have had for years,The pics are not great,Because my camera sucks.But this will give u an idea of what it is. The GREATEST STATE OF OKLAHOMA!!!
Maybe he is saying it is proof there are Ghosts. You can clearly see on the top of the first Picture it says " Ghost Towns of Oklahoma" and Why would there be Ghost towns if there weren't any Ghosts to live in them? See It must be proof there are Ghosts! Sorry, but I Just couldn't resist.
