Just wanted to get some thoughts about this particular route. I was curious since CA-1 merges to the 101 north of Fort Bragg. Is the rest of the way a pretty decent, fun ride? It looks like most of it is foggy one/two lane highway (per Google Street View), and wondering if it's small enough to enjoy. Not a fan of 3/4 lane interstates, especially since I'll be on a 150.
I am unfortunately planning against a schedule in mid September, since a friend can't leave SF until Wednesday afternoon but we wanted to be in Portland by Friday night to pickup friends who are flying into the airport. I think that's barely doable (around 380~ miles a day, camping along the coast at night), and I am not comfortable having to 'rush' or have no cushion in the schedule especially if this is a smaller highway akin to CA-1 that hugs the California coast, that takes more time to traverse.
Plan B right now is to take CA-1 south to LA so we aren't rushing too much, but this is a route I've already done so I'm really trying to see if making it up to Portland is realistic for us..
