Yellowstone national park is a place where people visit but it is also a Super Volcano. If this were to explode now, this is what the ash levels would be where you live.
Even if you survive that, we would enter a somewhat "nuclear winter" where the ask covers the sun. This is also how the dino's died. We would have about 3 weeks notice before it blows up so you could high tail it out and go far away but the traffic will be bad.
oh ya, Yellowstone is late for an eruption.
