It's been a year since I've been there but they did not have any at that time. If I remember correctly, I think we picked some up at the flying. J truck stop not too far from there before we headed in.
The last time I was visited, there was no potable water. The port-potties are not always up to date. The good news is that there's a Publix close by and it tends to be peaceful and quiet. I always had a good experience.
