Rough terrain, busy
The road into the campgrounds are very rough, small cars are not advised. There are only 10-14 sites available (first come first serve) depending what time of the year you arrive, since a pair of endangered owls nest between some of the campsites for a few months and will have the sites closed down. Be cautious of the stage of fire alert going on, when I went no campfires were allowed so I used a propane stove.
The surrounding areas are beautiful and a family of deer made appearances regularly. Also its free, so it was nice to avoid a hotel cost for the night.
The cons are that its hard to reach camp due to rough roads, very few campsites, and it seems the local teenagers really enjoy partying and screaming at all hours of the night. I assume you're better off on a weekday when all the kids are still in school.
