Another DX sighting, this time in Garwin, Iowa. DX gas stations once existed all over the Midwest until its parent, Sun Oil Company re-marketed the DX name into the Sunoco brand by the 1980s. DX signs and former stations maintained by petroleum enthusiasts can be found throughout this area. Although this particular building displays the familiar DX sign there is little else to suggest this was a gas station. Thanks to Garwin's Larry (without the S) for preserving the DX legacy in central Iowa.
