We spent a relatively quiet long weekend here on loop F 97, which is a bit removed from the main campground. It was a bit noisy on Saturday night but nothing disturbing. This site also is bordered by a small stream so expect mosquitoes and the occasional visit from wildlife (we had raccoons at our site each night, so kept food in the car). Each site has a fire pit and a picnic table.
There is a store just outside the entrance that sells ice, wood, groceries. There are quite a few roadside firewood sellers that are reasonably priced. The fire pit does not have a narrow grilling grate so bringing something to ensure your food won't fall through the widely spaced bars is helpful.
As I said, our site was out of the main population, but it was a bit of a hike to the restroom which is something to keep in mind if you've really got to get to a bathroom first thing in the morning.
There is a Walmart about 10 miles away in Gloverville, so keep this in mind if you are planning on picking up essentials when you arrive.
There are no sites with electric.
