The former super-tight connection between the Capitol and the California Zephyr at Emeryville is now impossible, as schedule changes mean that the Capitol now runs behind the Zephyr arriving at Emeryville after #5 leaves. (This makes sense because the Chicago train makes fewer stops between Emeryville and Sacramento than the corridor train to Sacramento, so the trains don't interfere with each other this way.) So an all-Amtrak routing requires taking at 10 AM train from Fremont and a connecting Amtrak Thruway bus to Reno. I don't like this one, but it does work.
Alternatively, I could leave the RV with Cory very early in the morning and walk the three miles over to Fremont BART, then ride BART up to Richmond to connect with the California Zephyr. This one is all rail plus a fair bit of shoe leather. It's not so much the walking that puts me off, but doing so with a heavy computer backpack and my luggage. But this is the plan I'll probably use if Lisa is for some reason unable to make the trip.
