I had to break out the Map again to answer some of my own questions and it just raised a few more. What I did notice from a google search is that there are several.. well, 5 airports in the southern area, not including LAX. Durai could be at anyone or all of them gathering equipment and planes.
I would also think they're headed southeast towards one of the big lakes like Lake Matthews or Lake Eisenore (sp?) near Terra Cotta.
Scratch and crew would head east on 210 from the Arena then turn south on 57 to E10, then link up with Durai at S71.
Lakes mean no water worries, food and fertile ground to plant.
