This is a loaded question. It depends on what a man and wife want for their children. Some look for a small school but want all the conveniences, amenities and interaction of a large city, thus the privates/"church schools"/home schools. Most UIl schools are rural. How rural do you want? Where? I'd personally go nuts in some of West Texas looking for a tree or decent hill. Some love it. You have to consider you own want's and needs too, especially regarding employment. you have to be able to provide for your children. Some want to get there kids as far away from "it" as they can (e.g. try Fort Davis). Does driving an hour or two to walmart bother you? I'd assume your interested in athletics AND academics.
I like the Strawn Gordon area. Good Academics. Good Football. The North Texas Hill Country. 35 miles to walmart and a few other dining choices, movie theaters in Mineral Wells or Stephenville. 75 miles to West Fort Worth or Abilene (the mall). Considering moving back after retirement.
