Amarillo grew to prominence in the late 19th century because the desire for railroad lines to be straight-ish meant that they had to pass through it. The city is in the Llano Estacado region, which means Stacked Llano, to be distinguished from Galveston and its stacked guano. Llano is Spanish, as Amarillo is too. The city is named for the charming armored animal that scurries hither and yon, selling unauthorized knock-off T-shirts at flea markets and standing in Home Depot parking lots in case work occurs. Amarillo is also home to thousands of Mexicans, who are identified by the things they do when pronouncing the giveaway double-L.
