Looks like this year it is in Clayton, Oklahoma in October. Found this on my facebook and thought I'd share. :-\

Here is some more detail taken from their facebook.
This is our 10th annual dual sport ride (formerly Ride Oklahoma) held in the rugged mountains of SE Oklahoma. We have over 600,000 acres of logging roads, stream crossings, two track and some single track riding. Great for street legal dirt bikes. Big duallies OK if good rider, but a lighter bike is better. We camp at Clayton Lake State Park and ride out from there.
