I should try that route someday. Probably in the spring. There is a nice bike tour of the Livermore wine country. It's not a long ride but fun and with a guide. The fun part is stopping at 4-5 wineries. It's arranged before the ride so the wineries expect the crowd. I have done it with about 20 other people. Very nice and not as busy as Sonoma/Napa.
