Hi,
I live 2 miles from the Pioneer Woman Mercantile AND the Calvacade Rodeo site as well as the Osage County Fairgrounds and 15 miles from the Tallgrass Prairie Preserve.
I have a HUGE driveway by my house in a very small residential complex on a main-county road. It is firm-packed gravel and my parents are easily able to park their 25-foot trailer then farm truck beside it just in that area alone.
It has access to a hose and an electric outlet. Wifi is available on request - have to make you a guest network.
This is a great last-minute situation if you suddenly need to be here in Pawhuska. Good for sleeping, eating, cleaning up, and going vacating elsewhere.
PERK: I am a naturalist and I do offer info and by-the-hour tours of the Tallgrass Prairie Preserve.
