To keep up with the times, Fox eventually converted his trolley car into a bus, as seen in this 1953 cartoon. However, the Skipper had trouble steering the new-fangled contraption around curves.
In 1955, Fox retired to Vero Beach, Florida, where he played golf and watched baseball's spring training camps. He died in 1964. His epitaph reads, "I had a hunch something like this would happen."
