I am looking for one night to tent camp in July near Covington GA. Anyone able to send me information on where a possibility is.

This is Charles Elliott Wildlife Management Area I camp there all the time in a tent there's no charge for camping https://www.google.com/search?q=Charles+Elliott&client=ms-android-mpcs-us-revc&sourceid=chrome-mobile&ie=UTF-8&inm=vs#tts=0

Hard labor state park is probably the closest to and best place to Covington

Hard Labor Creek state park would be your best bet, I'm thinking. It's in Social Circle, just outside Covington. It's a nice, quite camp ground, with bathhouses located thru-out and not far from stores and Covington. Checkout it's website.
