Utah was a recent new one for me.

Salt Lake City was unlike any other place I've been to. The train system is super cool for getting around. The highway system is well planned and isn't nearly as chaotic as other similarly sized cities. There are some interesting rules especially around alcohol. In a restaurant you can't just order a beer and not eat. You have to have food in front of you at all times no matter what. Overall kind people there in my experience but you can sense some friction between mormons and non. If you go hit up Ruth's diner for breakfast

Passing through the western border with Nevada there's a tiny town called Wendover. That border also changes the time zone so things get weird there. If you want to live Fallout New Vegas in real life that's the place to check out.

The Nevada side has a few casinos and marijuana dispensaries. The Utah side has most of the homes and an old WWII airfield used to train the atomic bomb aircrews. They also have the salt flats where land speed records have been set. You can literally see the curvature of the earth from the nearby mountains.

I think Salt Lake City is worth a visit with enough stuff to do and the beautiful landscape. I probably wouldn't want to live there though
