It's a bit of a drive to get there but give Mines Rd. in Livermore a try. You will not regret it. Start on the Livermore side early on weekday mornings. Over 50 miles to the top of Mt Hamilton and nothing but grins. One of the most fun times I've ever had blasting the twisty's.On weekends we hunker down at home. It's nuts on those roads on the weekend. It's nuts up there almost anytime, but I'm planning on some backroads runs, just lots of hazards there too, deer, cyclists, etc.
