Route 66: Clinton, Okla. to Albuquerque.

Conoco Tower is an art deco landmark along Route 66 in Shamrock, Texas, that once housed a gas station and a restaurant called the U-Drop Inn Cafe. Today the building still draws tourists, but it's used as the office for the Shamrock Chamber of Commerce. Built in 1936, it was the model for Ramone's House of Body Art in the Disney/Pixar movie "Cars." (Kate Snow/ABC)
