Charles William Post was an eccentric millionaire and inventor of the breakfast foods Grape Nuts and Post Toasties, and the hot breakfast drink Postum. In 1906 he bought 225,000 acres in Garza and Lynn countries near the Caprock in West Texas. In Garza County, Post created a new town, now called Post, and began experimenting with sorghum, milo and other grains. Post also spent a fortune on rainmaking efforts, to little avail, in the area.
