1927 Dodge Graham at the Shell Gas Station in Bodie State Historic Park. "Gold was discovered by Waterman S. Bodie in 1859. By 1879 Bodie boasted a population of 10,0000 and was second to none for wickedness, badmen, worst climate out of doors and best water on earth. Bodie is a preserved ghost town at an elevation of 8375 feet" (Source: Friends of Bodie water bottle label). Bodie was completely abandoned in 1932 after a second of two major fires destroys all but what is now left in Bodie. The Shell station sign is probably circa 1920's.

Back in the town of Mammoth Lakes, Shell gas is still being pumped at a much higher price than 20 cents a gallon of Bodie days. However, 20 cents then would be equivalent to $2.50 now, so filling up that SUV will still cost more than filling up the Graham truck.
