My sister and myself are booked on the California Zephyr for friday June 3. We are taking it to Sacramento where we will be getting a rental car from the airport and then traveling around california and heading up the Oregon coast. I know that through May the train is only operating 5 days a week with what appears to be no Sunday or Monday service. This is suposedly through end of May. I am wondering am I safe sticking with this friday leave date?
