While I don't disagree that they could be bored if camping out in the wilderness, I think it is sad that this has become the state of our country. Camping out in nature, the way man lived for years and years is now seen a boring venture. I could be engaged with nothing but nature for weeks and probably months, but obviously I'm in the minority.
I still think he has money, but even when he runs out, they could certainly start dumpster diving. Food stores throw out plenty of good food.
Right now, the trial of Eric Frein is going on here near me. He shot two state troopers and hid in the woods for almost two months before getting caught. He was a survivalist type and knew the woods around his home probably better than anyone. Still, he was in what isn't a very large area with troopers searching for him day and night. There was plenty of speculation that he might have got out of the area, but he was found in an abandoned hangar in the general area.
These two don't have Frein's skills and they are in a vehicle most likely, not on foot. Still, they have the advantage of much more possible locations and no one searching for them in a particular area, because no one knows how to pinpoint where they are. I think they'll eventually slip up and be caught, but if they are good at it, they could probably hide for years.
