You are more than welcome to come to the Lone Star state. I live in east Texas, two hours east of Dallas. I travel extensively for business. If I were to move and I had to rank the selections you gave, I would go with
1. Austin
2. Dallas
3. San Antonio
4. Houston
We have no state income tax and a healthy economy. Texas has everything you could want in the way of culture, geography, education, business, etc. I love living here. Feel free to email me privately for more specific questions/info.
My daughter moved to Houston from San Diego last April, and is finding it hard to get out and meet people other than her co-workers. She's 35, single, no kids, doesn't like the bar scenes and a little homesick right now.
She loves Texas, tho, and is glad to be out of CA.
