Really pretty much this. Not even the phone is going with me. I mean, not being able to check SR would suck, but the goal is survival, then being completely disconnected is the only real way. No stopping at the store unless I absolutely have to, no phone calls, no credit/debit cards.
Ultimately, the goal isn't a place in the wilderness. I'm not built for that. Goal is to get to a non-extradition country. Then figure out what next at that point.
That said, with a wife, kids and friends I know well, hopefully I never get put in a position where I'd be on the run.
