I am very familiar with this CG. My parents actually have a seasonal site there. Unfortunately, the CG has gone downhill over the years. The condition of the entrance road is atrocious surface-wise. Around 95% of the campers there are seasonals or construction workers (highway workers, oil/gas, etc..) It is a well-designed CG, with many level sites, Most of the full hook-up sites (E/W/S) are located in the lower level, and are mostly occupied with seasonals. If I were to stay there again, I would stay in the "lower" full hook-up loop (as far to the end of the loop as possible) or the electric-only section in the upper right area (more shaded and private sites). If you don't need sewer, I would recommend the upper right section (quieter and I prefer to be in the treed area). The CG is about a mile from Mountwood Park, which has pretty good trails (hiking and biking), decent picnic areas, and a decent lake). The park and CG were showplaces when I was a kid, but the funding is nowhere near what it used to be. They are doing an excellent job at bringing the park back up to par, and hopefully funds will someday be available for the CG too.
As mentioned before, North Bend State Park is much nicer (although a half hour farther from Parkersburg). NB has two CG's to choose from - one in the park along the stream (shaded, usually more crowded) and a newer one just outside the park in a field (very nice, no trees, bigger sites, and lake access). If you don't mind the extra drive, I would go with North Bend, as it offers better CG's, access to the Rail Trail, and an excelent lake. If you go with NB, I suggest towing on the Harrisville exit. The Cairo exit will take you along a very interesting road (nice drive when not towing).
If you have any more questions, feel free to ask.
