Sarah wrote in to say she's noticed trucks painting what looks like faint white lines on a number of major roads including viriginia street.  She wants to know what it is they're doing to the roads ?

What those trucks are doing is applying salt brine to the roads.   Michele Anderson with the city of Reno says they use it so does the city of Sparks and Washoe County as well.
  The brine is a mix of water and sodium chloride or road salt and it has a freezing point of minus six degrees.   
 They try to apply that salt brine to the busiest roads before we get a snow storm or deep freeze.   It helps to keep the snow from bonding to the roads and also makes it easier to plow once the snow starts to fall.
  There are a number of benefits. This brine solution is up to 20 times more effective than salt and sand its labor efficient since its applied during normal working hours prior to when a storm hits.
