It is the truckers on I80...most have never driven in snow and it is really tough on the open I-80...wind blows there all the time even in good weather...
I lived in Colorado Springs and worked in Teluride. one winter...got to Monarch Pass and the sun was out..and it said TRUCKERS chain up...well most did not because the sun was out...well they were all over the road when you got up on the pass..
Yes driver of snow many times in my country.
