Whats up all! Hwy 70 from Oroville to Hwy 89 is awesome! Very twistie and very beautiful drive through the Feather River Canyon. The stretch from Oroville to Lake Almanor took me little over an hour (I was driving conservatively since my wife is now 7 months pregnant and cant handle the twisties as well as before). Check it!
It would be fun to do a drive up Icehouse Road/Wentworth Springs. It would be an all day drive (I organized a Labor Day ride when I had my bike, and about 30 riders showed up), but we would start at Starbucks in Auburn in the morning, and drive up Icehouse Road to Wentworth Springs Road, and eventually end up on Hwy 50 north of Placerville. Take 50 into South Lake Tahoe, have lunch, and drive around the lake. We then jump on I-80 and come back down through Grass Valley and into Auburn. Probably one of the more fun drives, and there's lots of cool sites to visit.
