Earl - there have been several people who tried to open a feed store in Hearne. They were too expensive, never had what you bought last time in stock, and never had consistent operating hours.
allinow - if you are in Hearne or Gause area, your best source will be Producers Co-Op. You can also try driving down Hwy 50 from Hwy 79, just west of Hearne. There are numerous cotton gins along that road.
feel free to PM me. I'm located about 35 miles NW of College Station.
