Wow, I don't think I would have been brave enough to cross that four-lane highway.
What I always loved when I lived in snow country was not being able to see past the inside of the windshield. when that happened I would drive looking out the passenger side window to guage how close I was to the guarde rail to make sure I kept driving straight.
Really glad I no longer have to drive all those miles for a living.
Well, I was driving to a major automobile race track to instruct beginning race car drivers. ;)
