Automotive battery terminals get oxidation fouling in blast-furnace deserts just like they do in hell-holes of Hoth. It used to be a "no-loss" equation to undo the terminals from posts and brush them clean a couple times each year, but with the modern digital clocks and radios you lose all of your programmed settings. Marie whines about that; I point out that losing time-of-day and radio channels is better than a no-start in a dark parking lot at 10 P.M., and she grudgingly sees the sense in that. I do reset the clock afterward, in the interests of domestic harmony.
In Kalifornistan, the departments that maintain the roadways generally remove the road-kill in a given city or county. Cal-Trans handles the state highways and the U.S. highways by contract. In my county, Animal Control officers removed dead animals when requested by agencies or citizens, during weekday/office hours. Something large like a cow, horse, or wild donkey killed on a roadway would enable ACO call-out for removal "after-hours".
