The story about how Chicken Dinner Road got its name appeared in the Idaho Press Tribune in about 1992, and was reprinted in 2008. It seems that Morris and Laura Lamb were friends of Governor C. Ben Ross and his wife Edna. They had eaten dinner together many times at the Lamb home.
One day, in the 1930s, Mrs. Lamb, who was noted for her chicken, rolls, and apple pie meals, was in Boise. She invited the governor to come to dinner. During the same conversation, she complained to Ross about the pitiful condition of the road in front of their place, which was dirt pocked with potholes. Ross was purported to say something like, “Laura, if you get that road graded and graveled, I’ll see to it it’s oiled.
Mrs. Lamb approached the Canyon County Commissioners who saw that opportunity as a fine one. They graded and graveled the road. As soon as that was done, she was on the phone to the governor reminding him of his promise. The next day—this part seems unlikely, but it’s Mrs. Lamb’s story—the next day the road was oiled.
The story got around and local hooligans thought it would be droll to put up a big hand-scrawled sign in front of the Lamb house in the dark of night. It read “Lamb’s Chicken Dinner Avenue.” Mrs. Lamb was not amused. Still, the name stuck as Chicken Dinner Road.
Idaho Press Tribune writer Dave Wilkins penned the original story.
