Boondocking in the Ozarks?

I recently relocated from Greenville, SC to Bentonville, AR. I haven’t used my GFC around here yet and am struggling to find good spots to boondock (unlike western NC, near where I lived before.) Anyone have any recommendations for MO/Ozarks/Eastern OK boondocking spots? Thanks

It’s been a few years since we’ve been out there but I remember having to drive about 30 minutes out of town to find dispersed camping. The last night we ended up sleeping in the parking lot of a pizza joint in town (with the owners permission).

Have you checked the usual resources like ioverlander?
