I drove down to Napa Valley and stayed for couple days. There i found an old highway (still kept in very very good condition) that make a great riding experience.
Location : HIGHWAY 29 (north of Napa)
A.k.a = Lake Country Highway (runs through Robert Louis Stevenson State Park)
Length: Roughly 80 miles
Difficulty: 4/5 Stars ( Advanced)
Traffic: Very Low to NONE
Speed: 45 Mph to 65 Mph
Police Activity: None (at least when i went through twice , there was none)
This Highway running through a state park has a stretch of twisties with less than 5 straights (more than 200 feets) for 22 MILES. These turns are mostly sharp hairpin to sharp sweep. With a least 10 decreasing radius hairpin. Road condition is almost perfect with minimal gravel and loose stone. (It would rival mt. baker on smoothness)
(see picture / link above to see the series of hairpins - WOOT)
You can also do a loop of the highway if you stay in Napa. Which i did.
I was so upset because i was driving instead of riding. However, even in cage i had a lot of fun blasting through the twisty. I could image the fun i would have had if i was on my bike. *sniff* god damn it.
Stay : Hotels at Napa is way cheaper than i had anticipated. 3 star hotel at $80/night and 4 stars $95. Its worth it to stay there for a couple nights and attack the highway during the day. (enjoy some wine and jacuzzi at night)
Hotel : Hotel i stayed in is call Vino Bello. Has IN ROOM Jacuzzi !! for $125 a night with a bottle of free wine per night.
OVER ALL : AWESOME PLACE !! the only down side is to get there bike there.
At the hotel i met a group of riders from Michigan. They towed their bike all the the way from Michigan. Just for those highway.
SORRY i don't have any photo. I don't bring digi camera around.
