If you examine any good map of Texas, you’ll notice a natural division of East and West Texas that runs from the eastern side of the Panhandle down to Abilene and San Angelo and on past Uvalde to Carrizo Springs and Laredo. To the west side of that line is arid and to the east is wetter and greener. And it becomes increasingly dry as you go west and increasingly humid as you go east. Texas Standard commentator W.F. Strong explains the history of this geographical marker.
