Commentary – Road salt not only corrodes your classic car, but politicians as well

rusted 1979 Lincoln Mark V(by contributor John Bleimaier)…

In the culinary world, salt is one of a few truly magical ingredients which release taste and enliven sensory responses without relying on artificial chemicals that are detrimental to the human body.   Any chef that cares about the quality of the ingredients they use typically encourages the use of salt.  Thanks to salt’s ability to keep food preserved longer, it was valued highly in ancient civilizations because it made long-distance transporting and long-term storage much easier.  Salt was so revered that it was often used as currency – and the word “salary” is based on salt because workers would often be paid their wages in the form of salt.

Roads, bridges, storm sewers, all these are ravaged by road salt.  Works of civil engineering genius that might have survived like the Pyramids are laid waste within a cosmic fortnight.  This enormously increases the cost of government and provides yet another avenue for unscrupulous politicians and their cohorts to suck the life blood of a supine electorate.  Furthermore, in recent years we have heard many examples of vehicular accidents and loss of life that can be attributed to  crumbling bridges and roads?  Road salt worms its way into the retaining skeletons of critical structures – bringing them crashing down, almost without warning.

It is not only the timid who fear for the future in a world of environmental contamination.  Sodium chloride which is spread on the roads finds its way into our ground water where it’s extremely harmful to flora and fauna alike.  The next victim will surely be drinking water.

In other parts of the world folks use sand in order to provide traction on ice and snow. Of course, in an era when full-time all-wheel-drive and part-time four-wheel-drive systems are commonplace, frozen precipitation should be an ever declining cause of concern.  Furthermore, making skid pad training a central component of mandatory, universal drivers education would go a long way toward increasing winter driving safety.
