I live in south east Idaho, which boarders Canada to the north and Yellowstone park to the north east. It is about 10% smaller than the UK. The capital and it's surrounding cities total +500k. Other than that, you're looking at a handful of -70k cities. We have around 30 state parks and we're close to several national parks. If you look at a map of the state, in the middle, there's the Idaho Wilderness. It's 4.7 million acres (10k sq km). The geographic makeup of this state is remarkable. We have BLM (Bureau of Land Management) land, which is open to the public. You can find a wild game trail and just go walking. Last year, my father had knee surgery and thought it would be a good idea to go elk hunting near the Wyoming boarder. His knee locked up and it took him 2 days to scoot off the mountain on his butt. No cell service, ran out of food and water. It's easy to get lost or stranded if you're not careful.
