We're planning to travel to Boise from Seattle around Thanksgiving. Airfare seems kind of pricey for a 8 hour drive, but I am concerned about snow. I have no idea what mountain passes and elevation will be. We plan to leave around 11/22 and return 11/29. MApquest has us travelling from Yakima on I-82 and then merging onto I-84 in Pendleton Oregon until we hit I-184 in Boise. Is this the best route? What kind of terrain will there be? Should we concerned with snow. I drive a front wheel drive Saturn. Thanks in advance!
