I pulled in about 10pm last week (late October). I tried to pay online as per requested. I set up my 4runner and Roof Top Tent and passed out. There were ZERO other campers but a bunch of RVs. 

The Catfish bay campground was a super open peninsula with very little trees. There were human dropping buildings that looked clean but I didn't use. On the night I was there it was 68 with a very light breeze. I can see the summers being rough at this campground with almost zero cover. Nice shore line and my guess is the fishing is good.  

Probably won't return as I don't see this campground offering much.
