Well drove the Hwy H to Hwy O....I must say O was a lot better than H hwy. Tons of turns elevation changes ..... It's about 11 miles long and worth a drive. You should be able to hit every corner around 60mph+
. It has probably 10 25mph turns and about 7 or 8 30mph turns.
Going to try out some more next weekend if the weather is good.
Oh by the way DON'T take Z hwy at the end of O hwy in Orrick. It dead ends and the pavement ends
to a gravel road. Plus Z hwy is a real rough road....
