Full disclosure: I did not take this photo, but got it off the web site for the Paris civic center. I did crop it to focus on the tower and the veterans' memorial.
The COE at Airport in Waco is one of our favorites. We have two full service COE campgrounds on Lake 'o The Pines: Brushy Creek and Buckhorn, both near the dam. We prefer COE if they can fit into our timeline and itinerary for a trip.
For a visit to Natchitoches, Louisiana there is a wonderful new campsite called Grand Ecore, north of town which is one of the best. It is not exclusively a COE, but under the Red River Authority.
Here is their website:
