Wow! You're putting in a lot of hours on that project. Very nice. Looks like a beautiful area to make available to the public. And for orienteering?
Sierra Club works for 9 days each October on area trails: State Parks, Ozark Trail, and Roger Pryor Forest. I've put in 3 days each year for the past 3 years -- wears me out! They get about 15-20 volunteers per day.
Conveniently we get to stay and eat at Current River SP. CRSP is open only for Day Use except for work groups like ours which get to use the lodge, cabins, and kitchen. To upgrade sewer, water, and electricity for public use would be extremely expensive. It formally was the summer retreat for Alton (IL) Box and Board Company.
Orienteering? Roger Pryor Forest is privately run as a sustainable forest but is open to the public. It would be a large contiguous area for orienteering (or rogaine) but it is very remote - 3 hours from anywhere! Also, poor logistics. And SLOC is not now looking for such ventures.
