Yes it was extremely cold. I did not have enough antifreeze in my Dodge Cummins and she froze up on me. No damage fortunately. I believe it was down close to 5 degrees when I was there. Even after I got it running the heater core stayed froze for 2 days.
The freezing fog was interesting and the trip home down 97 to 197 down 216 back to 97 then over white pass was very interesting. Oregon side of 97 was really bad.
