Taking Highway 92 to Pacifica every day was SUCH A PAIN!
You're right that it's not that far from the city... I think it's something like 20 miles? But we get a lot of tourist traffic on Devil's Slide which slows things down significantly sometimes. Either that or the big trucks going to the jobsite.
They really upgraded Princeton Harbor, by the way (if you didn't already know). They have a big hotel (it's not huge, but big for the area) right by the HMB Brewing Company as well as a steakhouse restaurant called Crab Landing. It's worth checking out next time you visit.
