I would just ride if it's a nice day. 2 easy days to get used to the load, if going hwy 30 or 47. No idea of those road conditions myself.
I rode the Can/Am NW in 2018, was in Astoria on July 7. I then rode a short day to Seaside. There's a bugger steep climb going to Cannon Beach. I went up it with some walking and then said forget it to going down to the ocean and back to Seaside. LOL. From there to Forest Grove was 65 miles or so on hwy 26, 1 steep and 2 moderate climbs I think. Maybe 15 miles with slim or none shoulders, half is thru forest. Was pretty easy riding thru Portland, not counting the hills. LOL. I guess it's 45 miles from Forest grove to the airport. Not saying it's where you sould go.
Getting to CO mtn tops in late Sept. is iffy IMO.
