From History and Civics of Oklahoma:
Sallisaw (French, salaison, "salt meat"). That's also where we're camped -- Sallisaw, Oklahoma. Sallisaw is also the home of the fictional Joad family of "Grapes of Wrath" fame. It was also the home of Charles "Pretty Boy" Floyd. Sallisaw also got a "shout-out" from singer Brad Paisley in a song.
The first of the "Old Settler" Indians arrived in the area 1794, then the Trail of Tears debacle forced many of the "Five Civilized Tribes" out of South (map). The Trail of Tears saga was familiar to us.
Land was being sold at "Cherokee Outlet" on September 16, 1893, and the Sooners were those who jumped the gun.
End of lesson for today!
