Redwood Road in Castro Valley goes from CV to Skyline in Oakland or you can take a right on Pinehurst Road and dump into Moraga or continue on Pinehurst to the Northern end of Skyline where it dumps into Grizzly Peak in Berkeley and ride that to 80 North get back off on San Pablo Dam Road and head back south through Orinda and onto Moraga and then back on Pinehurst all the way back to Redwood Road and back to where you started in Castro Valley. Then stop at Val's burgers and get a burger and a shake. (wrc)
