I moved to the Dallas area from Pennsylvania two years ago.
There's a lot of positive aspects of living here. The job market is much better here than back home (not to mention my industry has a fairly thriving presence), and rent and living expenses are significantly cheaper. The weather is a lot nicer, the winters are warmer and it's usually sunny.
I really don't want to stay here permanently. I don't like being so far inland. It's so flat and nondescript here, and I miss hills terribly. I hate how everything is so new, in my day-to-day life I see nothing but never-ending strip malls, highways and there's not much in the way of historical architecture or interesting old buildings. There's not much nature to speak of, it's something you have to seek out. I'm not sure why, but the character of where I live means a lot to me, and it makes me feel like I'm living in some kind of giant biodome.
Also, terrible, terrible drivers on these highways. And gigantic, expensive cars. I've honestly never seen so many rich people before in my entire life.
Back in 2002, I was in San Angelo for a couple months while in the army, and my Texas experience there was fairly different from living in the Dallas Metroplex. It was a lot more stereotypically "Texasy", and even though there was nothing to do, the town was in some ways more interesting.
