We're going to be making this drive in eary September, was just curious about the route and the scenery. We'll be doing this with a 44' Diesel Pusher Thanks Trap
The route suggested by Google Maps is about the best way without going way out of your way. Very pretty too! Interstate 90 to 395 South West on 30/84 over to interstate 5 South to Coburn
I would highly suggest bypassing Portland by using South 205 around the city. Interstate 5 through Portland can be a nailbiter!
Easy Sailing as it is all good roads and light traffic excluding rush hours around Spokane & Portland.
