Hello David, welcome from Navina, Oklahoma. As
@ryanorr280 mentioned, the Ozark and Ouachita National Forests are generally the go to places. You might also check out the Oklahoma Adventure Trail (OAT) that circumvents the entire state. What kind of Jeep did you buy? If you are interested in a local Jeep group, might I suggest Frank's Jeeps on Facebook.
You are in the Southwest Region. Check out the
Southwest Region sub-forum for local information and involvement opportunities.
