For you guys that live in San Jose area...
Go down 680 to milpitas...take the Caleveras exit towards the mountains...and just keep going. Then take a left on Caleveras when it branches off...
You'll end up in Sunol 30 mins later...it's one of the scariest roads in the area because it's only 1 lane 80% of the time and half the areas dont have guard rails!
theres also a nice view of a resivoir so bring a camera...5 mins away from home and its like a different world!
Expect to waste 1/4 tank of gas and make sure you have good tires...it's REALLY windey.
The first time I drove it a mazda protege was keeping up with me...
