The Rhome (TX) Phone Company in 1977 had 400 customers and 3 employees. The book was pretty small. In Rhome and Decatur I always requested a party line as they were cheaper. Everybody else in town would request a private line so I was the only one on my line.
Party lines cheaper, ah yes-- hard to believe that really wasn't that long ago. Way back in the days when you waited until after 5pm or even better, after 11pm to make that long distance call to save $$$...
