Duane,
I always go down 395 from Lakeview Oregon, the rds is great, wide open with very little traffic, slow down if you see on coming traffic as all the radar there is from moving policed units as the space is so wide open, you can cut over from just south of Portland on I5 to sisters Oregon to Lakeview 395. The weather is always better this way and the distance is about the same as I5 to Reno. The second year of the bash I drove this way home and saw no rain, as Fred, Brent and the others had lots of rain up I5. If you dont drive up 101 this is great second choice.
Like Jim says the weather can be anything, last year we had a great fall, By the way what is HC1?
