My wife has had enough of the cold weather and wants to head out to Yuma from the Missoula area within the next 2-3 weeks. I assume 93 south once the passes in Idaho are OK. Any route recommendations ...
Having traveled in cold country a lot I would recommend staying on interstates unless you are familiar with secondary highways and watching weather reports closely. Several years ago I was heading south from Missoula and got directions from a local person and almost got stranded in a snow storm. Neither that person nor I was aware of of a storm coming in. Be careful. Interstates are monitored and plowed regularly, secondary hwys are not.
