One of the worst driving experiences ever, was last January in southern Indiana on the new I-69 north of Evansville.
Turns out that the State accepted the road salt restrictions from the EPA to preserve wetlands, limestone caverns, underground streams, and eagles.
But at the risk to car drivers and passengers (aka humans).
There are signs “Low Salt No Spray” posted. As soon as we encounter these areas, the ice/packed snow on the road became very dangerous. It sure felt like Low Salt meant No Salt.
Had I know that this restriction existed, in the hilliest area of Indiana, we would surely have used I65.
The Politicians want the “NAFTA Superhighway” so bad that they seem to be willing to risk people's lives to be able to have it.
