Last I knew #4 was NOT built into a house. It is located on a residencial site just north of town. Since it was moved there the trees around the site have grown up and it is difficult to see when driving on the highway.
There is another passenger car of unknown origin built into a residence in Keeler. It is on the southeastern most street (the one running perpendicular to the highway and closest to the talc plant). The car is aligned with the highway and the old railroad several lots (toward the highway) away from where the railroad ran.
