The Real Gas Farm and Hurley Residence

From what I gather, the gas station that was used for Big Ed's, located on Preston-Fall City Road, closed not long after the show first aired in 1990. The gas pumps were taken out and the building underwent several drastic changes of business and architecture (one business was a windsock store). Last I checked, which was February 2007, the building was still occupied by Stone Age Rockworks, a stone and tile store.
Below, a good example of the contrast between the original Washington locations and the California locations used for the rest of the show –Big Ed's Gas Farm from the pilot, then from the series:

The house next door, used as Ed and Nadine's, was not affiliated in any way with the gas station, but it was a rather ingenious idea to connect the two for Twin Peaks. It seems a logical pairing.
