Are European tourists lining up in droves to visit Dallas, Houston, or Chicago? No. That's why they are cheap. Because the quality of life is awful.
Houston is disgustingly hot and unwalkable. You have get on a plane to ski, mountain bike, or go to a nice beach. The traffic is hell.
Ditto Dallas. What exactly does one do in those cities? Can you backpack, hike, walk, ski, lay on a beach? Like, I guess they are OK if you like being stuck in traffic on your way to a bar. But what else is there...to do? I've been and I could not understand the appeal? There was all the inconvenience of a big city and none of the amenities. And no outdoors.
Chicago (worst years of my life) is crime-ridden, uncultured, and once again you have to get on a plane to ski, mountain bike, or go to a nice beach. Bad traffic, mediocre transit. It's great if you love football and beer, but that's it.
