Looking at your route, I'm jealous. I used to live in Westlake Village not far from Decker Canyon and I used to love early morning runs out along the Mullholland "dragon tail" Of course back then it was in a '73 914 2.0 that ate that road for lunch and asked for more. I don't miss the surprise landslides that left valence crunching boulders in the roadway but still it is an incredible stretch of road. you have to love how you can sit at numerous turnouts and look down at the road winding through the canyons below.... Would make for some great video....HINT HINT
Have a great time!
