I went ahead and bought a roundtrip to PNS. It's going to mean a long drive up from Durham but I've been meaning to go to the Museum of Naval Aviation for a while and fares out of RDU have been really high to PNS. Even with a hotel in the D.C. Area and two tanks of gas this will be less. Plus, when else am I going to fly DCA-PNS on an awful CRJ-200?
