Grants Pass to CC on hwy 199 is a blast if not busy, great BMW road! Might find a CHP near CC. From CC to Monterey is some of the best driving in CA, if not to busy. I used to always try and come through here early AM, V1 on. Big Sur? Nirvana! But pretty busy during the summer though. When I lived in WA and had my e39 M5 I made this drive a couple times a year visiting friends in San Diego. WA and OR seem to have lots of patrol coverage, not as heavy into NorCal usually.
