From San Francisco, our next stop was Chicago. When we were planning our trip, it seemed silly to cross the country and miss everything in between so Bella and I went an unconventional route and decided to take an AMTRAK instead of flying. The California Zephyr is a 51 hour train journey that crosses 7 states - California, Nevada, Utah, Colorado, Nebraska, Iowa and Illinois.
Seeing as the train ride was so long, we rode the Zephyr from Emeryville (near SF) to Denver and got a sleeper carriage (30 hour ride). We got off and spent a couple of days in Denver before resuming our journey to Chicago in coach (another 20 hour ride).
