The population of Houston, Texas in 1960 was 1,364,569. By 1980 the population was 2,754,304, or slightly more than doubled in twenty years.
A reasonable argument can be made that the period from 1960 to 1980 marks the end of the Texas frontier era, and the beginning of the modern Texas era. My family moved to the Houston area fairly late in that period. I remember reading the daily newspaper (we were a Chron family), and it seemed that there were giants in the earth in those days. Carol Vance was one of them. Boomtown DA
