Driving across the US on I-80 in Winter
I got a job in Portland, Oregon and I need to drive across the country to get there. I've driven across I-80 before but I have never done it in February (or later than September). I'm hoping the GWJ hive mind has some tips or advice about any potential trouble spots along the way. I'm thinking about crossing the Rockies in particular. I am really hoping to avoid going south (I-10 or I-20) as that would add multiple days to the drive.
Does anyone know of any cross-country driving in Winter resources?
