Funny that I'd read the post from July 13th because we were there the following weekend and experienced the same problem. We arrived on Thursday night with intentions to spend 3 nights. There was a very loud and rambunctious group that partied until we packed up and left at 11pm (I'm sure they continued on for longer). The thing I learned is that when there's no campground host it can be more of a problem. The sites were small but nice, pit toilet bathrooms smelled horrible, but the creek and swimming area behind were top notch.
