 After returning to Earth in Episode 7 ("Thats All There Is"),  astronaut Dick Gordon comments, "Id just like to go to PeTes and  get me some Cajun barbeque!" PeTes is an actual Cajun barbeque  restaurant on Texas State Highway 3, just outside of the entrance to  Ellington Field, in Houston. It still exists today and is frequented  by many current members of the astronaut corps.
