While that was an awesome route, there is a good alternative (shown in pink). We rode it personally this weekend and it's plenty fun. About 70-ish miles from the LA area and is packed with lots of elevations changes, twisty roads and very little traffic. Just the ingredients needed for a nice Saturday morning ride to the Chop Meet.
For those of you coming from the 15, or the 14, this won't have any impact on your route.
