Just realised that I never posted the video summary of this trip:
The video is mostly roads and scenery so that I can remember the routes for next time!
Southern California proved to be a great place for tourist biking. It's possible to go from ocean coast, to mountains, then desert in the space of a day. Roads were curvy and grippy, with lots to see. I enjoyed this short trip a lot more than my other USA biking trips (Cal valley and Yosemite region, and also route 66 run).
My favorite bit was the last day over San Jacinto. By this stage, I had become familiar with the hire bike (twistedroad.com was great) and was able to push a little harder. I went up and down the mountain a couple of times.
Many thanks to Miles for providing liberal route tips during my stay.
