I have to take a trip very soon or lose close to 20,000 points. I can always drive to Davis and take the train to Sacramento or Martinez (Davis has better parking than SAC). But I could also drive an extra half hour to Stockton and take the train to either Antioch or Fresno, two places I've stopped in a car but not a train. Both Antioch and Fresno look like there are interesting places to visit near the station. Any local knowledge to confirm or deny that, or suggest other destinations?
