It makes me tired just to think how many miles Glen Clopton and his colleagues spent behind the wheel of an automobile during their time on the Highway Patrol. In the early 1950s, for instance, Glen’s patrol car was due for overhauling. In 22 months, it had been driven 103,377 miles (70% of them by Glen), an average of 4,695 miles a month. Those cars, Ford DLs, used 13.3 miles per gallon and operating cost was 3.2 cents per mile. (I don’t know for sure what gasoline cost per gallon back then, but I’m sure that today’s prices would have boosted that operating cost by a bunch.)
