While staying at the Edwards AFB FamCamp, CA, I discovered they also have a primitive campground available. Branch Park is open to tents camping only. There's also a small fishing pond and picnic area there. I have no clue why this small camping area has never been mentioned before. It's primitive camping - no water, electic, sewer, phones, showers, or other facilities. However, there are porta-potties available.
