This is a very nice free campground that would typically cost at least $20 per day. The road and parking pads are paved and there's a restroom and dishwashing area. Although most site pads are fairly short, I was able to fit my 35' overall rig in sites 2 and 16.
During my stay, 90 percent of the campers arrived early evening and departed early morning so the campground was empty each day. I did not have any AT&T data.
Note, stay limit is 7 days per year.
