It was worth the cost
First: Be prepared for a lot of road traffic. It is a popular launch/takeout location for fishermen. Most fishermen towing boats drive through the campground responsibly,
but there is a lot of locals I suspect, cruising the campground and dock areas that do not. The sites are on a hillside so uphill backing is required for most sites. They are concrete and relatively level. The water and electrical hookups were good. I had great AT&T cell service. The dump station left a lot to be desired. It was basically an open septic tank that was really full, with just a chunk of sheet metal and a rock covering the opening, which was about 18-24" x 18-24". The water was located about 25' behind the "black hole" and needed a long hose to connect for flushing. As someone not averse to black tank dumping, this one even grossed me out. My campsite had a great view of the lake with some pretty sunsets and sunrises. The camp host was very nice and helpful and showed me to my campsite when I arrived. This was good, because the sites are not well marked. The biggest downside was the wind. Very high winds even for Oklahoma.
All in all, it was a very quiet and peaceful week for just relaxing and enjoying watching the many birds frequenting the campground and lakeshore.
