>>650465Canada and Russia are the best I'd you REALLY want to leave civilization, but I wouldn't say that's the only definition of being /out/.
If I had to pick a country, it would be one that's most diverse. The USA is probably the most diverse country geographically on the planet.
USA has arid desert, high snow covered peaks, vast plains of grasslands, temperate forests, rocky cold coastline, tropical islands, warm Sandy beaches, artic tundra.... a huge selection of stuff to go /out/ in.
Other countries that may come close would be Brazil due to the huge rainforests, Argentina with its mountains, plains, and coast, Australia with the vast outback and coastlines, even China with its varied terrain.
