Instead of turning left on Greenfield and taking LaCresta up through Crest, I recommend taking the I8 business rout to Old Highway 80 and intersecting Arnold Way.
LaCresta is a killer hill, quite literally. It is steep as heck with alot of blind corners and cars drive it like they are on a race track. There have been many wrecks and deaths on that short stretch of road.
The rest of the rout would not be too bad except there will be alot of sections that have no bicycle lane. You will be right lane'n it with traffic at 55+ on your left. Bring plenty of extra innertubes! There is alot of crap alongside those roads.
