We are military and want to try and go home for Christmas and driving is much cheaper than flying. We are in the Olympia, WA area and will be driving to Vacaville, CA which is not far from Sacramento. I am worried about doing this drive because of winter weather and passes being shut. We would be on a certain timeline because my husband would have to be back, by the end of leave. I don't know if we should just plan on sucking up the cost and flying, or is it really a big chance if we drive. We would be driving an 09 Toyota Corolla. Any tips or information would be greatly appreciated.
