LOL I grew up in Nakusp BC and know folk that lived like that. Very hard to hide these days.
A large bulk of the town were draft dodgers due to vietnam.
Was in Nakusp once in the 1980's for the hell of it. Cool little town, nice mix of people.
As far as Vietnam draft dodgers, Likely had about 3 or 4. As far as being off grid, it was very easy then - and people are still doing it. If you're younger than 20 or 30 though, yeah, it's improbable if not impossible.
Based on the length of my response, I'm obviously on dial-up .
