No, not Mickey Gallivan of the Pomona Historical Society — Mickey Mouse.
John Clifford of Pomona found the cartoon “Mr. Mouse Takes a Trip” on YouTube. The 1940 cartoon begins with Mickey and Pluto attempting to board a train in Burbank (“Elevation 16 3/4 Feet,” says the sign on the depot). At the end of the cartoon, the conductor throws them off the moving train.
“Gosh, Pluto, I wonder how far it is to Pomona?” Mickey asks, dazedly. Then he looks up and sees the sign on the depot: “Pomona, Elevation 6 3/4 Feet.” He squeaks: “Pomona! Hey, we’re here!”
Or as the German Dutch subtitles in this version render the conversation: “Jeetje, hoe verzou ‘t zijn naar Pomon…Pomona. We zijn er.”
