COULD SOMEONE TELL ME THE BEST ROUTE FROM YELLOWSTONE TO CRESCENT CITY CALIFORNIA. MAP QUEST LIST TWO ROUTES. I-90 THROUGH SPOKANE WASHINGTON OR 84 THROUGH BOISE IDAHO.
I90 will take you all the way to Seattle and then catch 5 South to central Oregon and then West to101 on the coast and south to Crescent City. That's probably the fastest since your on major interstates. Personally I go south on i5 to Kelso/Longview, WA and catch 30 West to the Oregon Coast and then go south on 101. Much prettier drive but a bit slower.
