I will be moving from Knoxville to Seattle in the next couple of weeks and want to do this as a road trip (my furniture will be going separately by movers) as opposed to shipping my car. I can't find anyone to go with me and being from the south, I am not equipped for snowy driving - my car is not AWD and I don't have tire chains, nor do I know how to put them on. I want to take the route going through St. Louis, Kansas City, Denver, Salt Lake City and Boise just to see some places I've never seen. I know I can't predict the weather, but am I likely going to run into problems snow-wise? Will I be going through mountain passes that require tire chains?
