Weather conditions late September, driving South?

[Bartruff1]

by the route....I would say 1-5 most often would have the best weather but boring as hell....97 would be colder in the mornings but also pretty boring..the coast 101 is spectacular if the weather is good but it can change quickly and the traffic can be annoying...in the early fall I would take 395, neat little towns, little or no traffic, wide variety of mountain and farm scenes and GREAT 2ND AND 3RD GEAR WINDING UP AND DOWN ROADS !!! If it is the Journey and not the destination....that is a superb motorcycle sports car route, the roads around John Day will make you laugh out loud...The people there seldom (if ever) see a Cobra so you will get a lot of questions at gas/meal stops ....go for it but check with ODOT to make sure they are not sanding or spraying for frost in the canyons and passes.. ...

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?
