where in North America would you build your hideout?
Pretend you had unlimited budget.. given the event of population collapse some time in the next 25 years, if you spent the time up until that moment developing a fully secured self powering residential hideout for the purposes of staying isolated where and how would you do it?
many people from the states would probably start coming up to Canada given they were easily crossing the border means that places in the southern half of Canada would probably be bad places to try that in. being a Canadian, I say going up as far north is you can would be a good start, but it also means you probably end up freezing to death if anything happens to your power source.
