Haven't been on 38 this year yet but 99W to Rickreal and then cut over to Hwy 223 (Kings Valley Hwy) and head south to Philomath. At Philomath get on Hwy 34 west. Gives you a little more scenery and curves than slabbing all the way down 99W to 34.

If you have the time, at the Alsea summit take Mary's Peak Road up to the summit and back down. Favorite sport bike road detour. Have never followed it past the summit as I believe it becomes gravel.

Safe travels.
