Avoid site 51.
There is a maintained walkway from the restrooms through site 51 so unless you like foot traffic all night choose different site; I recommend site 52. The host let me change sites with no hassle. Thumbs up to the host! Yes there is a little road noise, showers are $2.50 in quarters and they weren't selling firewood when I was there. There several good hiking/biking trails close by. Don't forget your earplugs and pocket change .
Happy camping!
