Did the first year 23. you will definitley catch some rain. Samoa is always damp in the morning as is Coos bay. they do a pretty good job on drying. Just plan for rain. It was a great time and great people.
I work in Coos Bay and Eureka and you are correct on the damp/wet. Samoa is basically in the Ocean. Coos Bay is in a damp valley across the street from the river. Even with those factors there are fast cars that get down those tracks without issue. Samoa is not on the list this year. I will be surprised if they make the route go down 199 back up 101 to get to Coos Bay.
