"The Chicken Ranch," or Miss Edna's Boarding House in La Grange, was probably the oldest establishment in Texas, catering the the oldest profession. It was closed down by a zealous TV reporter from Houston, who couldn't find enough vice and corruption to report in Houston.

Miss Edna's girls had weekly visits from the local doctors, so they were "clean." The girls spent their money in La Grange and when a new hospital was needed, Miss Edna gave the first and largest donation. The reporter remained on the air crusading against such hideous crimes such as slime in the ice machines of restaurants.

were allowed in.
