I'm looking for fun roads to learn to drive my RS4. Here are several options (putting together all suggestions -- thanks to s4wood, TwentyValveB5+S4, GotRS?, and onrails):

* Hwy 9 from Saratoga heading up to Skyline (Hwy 35), then North to Hwy 92: map
* CA84 from CA35 to PCH: map, youtube1, youtube2
* From Castro Valley to Milpitas, through Palomares, Niles Canyon, and Calaveras: map
* From Castro Valley to Moraga via Redwood Road: map
* Big Basin Redwoods State Park (fun side is coming from San Jose): wiki, map
* Mt Diablo: wiki, map
* Mt Hamilton: wiki, map
* Highway 17: wiki

Any other ones, guys?
