We go there every year. We take I-10 to I-49 in LA. I-49 to I-20. About Tyler TX, take I-69 North to Greenville TX then pickup US 380 West to Decatur TX, then I-287 North thru Wichita Falls TX then hop on I-44 to Lawton.
We usually fill up at half a tank so we don't have to worry about finding fuel. Look for truck stops on the interstate highways. We like Flying J, Pilot or Loves. Petro and TA "so-so"
Flying J I-10 exit 192.
Pilot Travel Center I-20 at Tyler TX.
