Uncle Earls is in Winnfield; make the two hour drive south on I-49 and eat at Prejeans.  Best food I have ever had.  Visit Natchitoches; small town with a lot of scenery and good places to eat.  If you have time, visit New Orleans; it is a different world and a lot of fun to visit.  Some good casinos and a nice boardwalk in Shreveport.
  Do this.
