Pretty soon it’s going to be at the point where I-35, from the Oklahoma border all the way down to San Antonio is going to be populated....there used to be a lot of open areas, not anymore, the cities are blending more and more into each other.

True, but the population boom/band stretches about 30 miles to either side of 1-35. Go any further east or west and it thins out again to rural communities.

There's a similar population creep moving eastward along I-30 from Dallas.
