After reaching the other side of the pass, the refugees would coast their vehicles down the other side to save gas. If the refugees needed gas, a man named Ed Edgerton ran a gas station complex known as "Ed's Camp" at the top of the pass. Most of the time, Edgerton was willing to barter with the refugees if they had little or no money. Sometimes, the refugees would trade or pawn valuable possessions to Edgerton for gas. Other times, Edgerton would have them work jobs at his station to earn their gas. Upon reaching the other side, the refugees would often establish camps along the Colorado River near Topock and Needles on the California side before continuing their journey. The rest of the route through Arizona was also difficult for refugees, due to the extremes of the desert heat during summertime. Famed author John Steinbeck would later go on to describe some of these experiences in his novel, "The Grapes of Wrath". Part of the novel detailed the experiences of the Joad family, a fictional refugee family from Oklahoma taking US 66 through Arizona to California. In 1940, the novel was adapted by 20th Century Fox into a movie starring actor Henry Fonda as Tom Joad. Several scenes in the movie were filmed along US 66 in Arizona, including scenes where the family crossed the Arizona–New Mexico state line near Lupton and the Old Trails Bridge over the Colorado River in Topock.
