I don't understand how anyone CAN"T believe they haven't gotten to the west coast or to Mexico by now. It's been 3 WEEKS since they were in the OKC WalMart and it only took them 2 DAYS to get there. I honestly believe they are either AT where they were originally headed or very, very close by now to being at said location. 3 weeks is a long time since the last sighting. You can travel a longggggg way in that amount of time.
And I've seen people talking about the money and how he's going to run out of it soon. Why?? All they are buying is food and gas. And if they get to where they were going, or are already there, they aren't buying much gas anymore. They don't have any other bills to pay like we do. You can buy a lot of food with 4 grand for only 2 people. That money could be stretched to months and I've seen people saying he'd be running out in days. Really?? They aren't eating steak dinners folks.
IMO, and I hope I'm wrong, I don't think they will be found for quite some time since they haven't by now. It's obvious he's not going to just bring her back on his own free will otherwise he'd have done it by now. I'm not sure if he would IF she wanted him to right now either because like others have mentioned, he's given up everything for this sick fantasy of his, he has nothing to come back to besides a jail cell. So IMO, if she eventually grows tired of being isolated from everyone else she cares about and asks him to bring her home it's doubtful he will oblige. My hope in that scenario is he just makes a run for it and leaves her wherever they are at OR takes himself out and doesn't harm her.
And last, going off my belief that they won't be found for quite some time, I think it'd be imperative in roughly 9-12 months, IF they haven't been found by then that is, for all hospitals etc to be on the lookout for any young gals that resemble ET showing up.
