Texas is in an odd position in people's thoughts. Southerners excluded it from the "real South" and westerners regarded it as just "Texas" or Western if you were talking about the Texas Llanos and plains. As a source of cattle, it was often lumped with northern Mexico which also produced cattle that were herded west and north. After the Civil War, Southerners considered Texas to be the place to which you went if you were in trouble.
