I think Alaska would be interesting, but because its in between Alaska and canada, make it Northern Canada. Or even a track from Niagra Falls upwards, to parts of Canada that are uncharted. The part you only see on National Geographic
Uncharted? Canada is and has been fully explored like the rest of the world, beside the oceanside, maybe you mean areas where people dont live, civilization.
Though a good place for Canada Fallout would be , Vancouver B.C I think with many areas for an Rpg game.
Mountains(Ski slopes)
The city itself
Stanley Park )an isl small military base with many fun area to explore. aquarium
ocean
and other exaples that I'm to tired to bother with..
Niagra Fall Is ALSO a great area to.
