I camp there a lot as long as you don't get carried away they do t say anything, just keep it on your site, and don't have bottles sitting on picnic tables.
That is what I understood from all the signs. We don't drink, so it was no big deal for us. I think they emphasize it being a family oriented campground. Nice place to stay.
