Yeah, I had Google plot it and they're mental-- I remembered why I never let Google plot routes for me. I'm a "let's take the most direct route" guy-- I would take Jamboree all the way up to E Santiago Canyon, and follow that to Cannon; then Cannon all the way up past the 91 and get on the SART there. I'd go past Green River and all the way through Norco to Hamner, and just take Hamner all the way across the valley. There is no sane way to go through Chino/Chino Hills-- I don't even like going on the 71 in a car, and Google wants you to take access roads over the hills.
