Legitimately, the Mountain West. I am super biased because I grew up in Colorado but I think the Mountain West is something in America that should be truly celebrated. The small mountain towns are incredible. You get roughly 6,000-10,000 people together living in a valley and they decide they want bike paths and rec centers and decent bus service. The towns are small and walkable and there is a lot less sprawl. Property lines might be defined but people are more lax about things and walking past someone's house to get to a trail isn't a terrifying adventure in will they shoot me or not? And then the outdoor space. Everywhere I lived outside of Denver I could walk down the street and be in a National Forest in less than 10 minutes. Some places I could walk off the property and be in a national forest.
It's crazy to live in a big city now and I feel less safe riding my bike to the store despite it being 10x closer. Getting outside and walking is so much easier because there is space that isn't "owned" by anyone. It's freeing for the mind and soul.
There are problems but when I moved away a few years ago even the people on the trump train we're still community members looking to support everyone including gay people, trans people, and women. All the opinions I heard were summed up by, "Well, it's their choice, it don't affect me."
Let's celebrate Canada's mountain West too! I guess I'm not saying this is unique to the US just that it is something that is genuinely worth celebrating. That's actually the question you were asking, what is genuinely good.
There's a lot of bad to focus on. The Rocky Mountains are both gorgeous and worth protecting and the ancestral home of native people that our ancestors murdered in order to claim.
And yet, I think it's cool to actively look for good things, not as a distraction but to try to understand what we want to have more of and what makes something special. Especially with the US feeling unsafe and unstable.
