I live very close to Osage County, just across the Arkansas River to be precise, and yes, there are a lot of Ghost Towns there, depending on where you grew up in Osage County. Some of the old towns are becoming more and more of a ghost town, like Grainola, Webb City, Foraker.... but they are not ghost towns yet, just slowly browning vacant over the years. But there are a lot of Oil Boom Towns north of US Highway Sixty almost straight north of Fairfax, such as Hardy, Personia, Whiz Bang, Lyman, and I forgot the name, but an old fort when it was Indian Territory, and a lot of stuff to find. Elgin Kansas is just to the North of the Tall Grass Prairie, one of the places where they hung outlaws in the mid to late 1800's, with brick streets and dirt roads leading to it, and while it isn't a ghost town, it is pretty much vacant these days with a lot of mown areas to shoot for relics and coins, but at one time Elgin KS sported 6 gallows along Main Street. Be sure to ask permission though, for the true Ghost Town sites are now on private land, you can get the assay for the area from the Court House in Pawhuska to find out who owns what these days. A lot of the old ghost town areas have cattle on them now, and the bulls are not quite the most gentle of animals, and ranchers want to be sure you cover your holes so the cow doesn't come up lame.
