I don't know how far you like to ride but if you want some more good riding continue up 33 towards Taft and take Hwy 58 to the coast The scenery through the oil fields on 33 isn't the best but 58 is great (gas up in Taft because there's no services on 58)
Or try Cerro Noroeste Road towards Frazier Park, on your map it's the road marked in yellow. The asphalt is smoother and cleaner than Lockwood Valley Road and they end at the same place.
I'm trying to make this ride but I've been on the road almost a month and not sure the wife will let me leave without her for the day. How many are going? How crazy is the pace?
