I am going to be traveling to Whitefish, Montana from Santa Barbara, CA at the end of December and am not sure which route would be the safest. I am not very comfortable with winter driving so I want to go the safest route for someone with little winter driving experience. I was thinking of either going up I-5 to Portland and then taking I-84 to US 395 to I-90 and up to Whitefish or taking I-15 up to I-90 and then on to Whitefish. Does anyone have any tips for making this trip this time of year? Thanks!
