X2 on Petit Jean State Park near Morrilton... Been there a few times myself.... Love the Arkansas River area along that stretch or the country side south of I40... Many camping location here...
Was stationed at LRAFB back in the 60s and ran the Missle sites all North of I40 doing Radio Maintenance. We all found out real quick you could find a new fishing spot within 30 minutes of any direction you wanted to look haha... All of us Air Force Radio Maintenance types carried fishing gear and always took the long way back to the base when done with our maintenance at the Missle Silos haha...
