Post is the seat of Garza County, and was named for C.W. Post, the cereal manufacturer who founded the town in 1907 to demonstrate his economic ideas. Post was designed to be the center of a community of farmers who owned their own land and homes in a region of giant ranches. All supplies were first brought in by mule train from the nearest railhead, Big Spring, some 70 miles away.
Between 1910-1913, Post was the scene of perhaps the most elaborate series of experiments in rainmaking ever undertaken in the United States. Explosives were detonated in the atmosphere at timed intervals. Unfortunately, rainfall records do not indicate success.
Post is at the foot of the majestic Caprock in the southeastern edge of the Great Plains of the United States. Its historic Main Street is lined with gift and clothing stores and restored historic buildings.
