I wasn't available on Sunday afternoon (family activities) but I actually drove that exact route on Sunday morning...starting from the Lick observatory and going north, ending in Livermore. Nice drive. Hopefully next time I can join you guys.
I'm kinda curious how your drive went with multiple drivers. Driving solo, I can go as fast or as slow as I feel comfortable, and I frequently pull over just to admire the scenary.
