Well, I'll give it a stab, but it will be a VERY long route.

First, if you take I-40 you will need to get off I-5 in Sacramento and head up the coast on 101 to avoid going over the high passes through the Siskiyous.  Come back to I-5 at Eugene, OR, and then to Portland and down the Columbia Gorge to get to  Spokane.  You may have snow in Eastern WA anyway. I'll pmail you the link.

That's 2700 miles according to Mapquest, so I don't know how badly you want to avoid winter conditions.  It would be cheaper to have the car delivered.  Here is one place to get a bid:  www.montway.com.

Subject: winter driving to Spokane

I may need to drive to Spokane, Washington from Edmond, Oklahoma in December, maybe late December.  I have been trying to work out the safest (meaning least likely to encounter serious winter weather) route.  I may have settled on driving a long way  around route involving taking I-40 to California, then up I-5 to Portland, then from there back NE to Spokane.  Or even dropping further south to hit I-10 and I-8 to get into California.

These are likely to involve at least 5 days of driving,  more if I do hit winter weather on I-40 (quite possible anywhere along that route until dropping off the plateau at Kingman, AZ) or even on I-20 in Texas.

Anyone have anything to suggest, including taking my chances through the plains and mountains rather than one of the these long way around routes?

Of course we would be winter prepped, with proper tires, emergency gear, food and prepared for multi-day stops if necessary.

My apologies, but this drive will not involve my camper, which has already been moved to Spokane, but rather my Prius.

Thanks, Dave McNeely
