Between Aug 28 and 31st, I will be in San Francisco with my family. However, I won't leave out any sort of transitfanning. I am particularly interested in Caltrain, Amtrak operations, and bart. Any tips?
You can do a "circle trip"...
BART to Berkeley
Amtrak California to San Jose
Caltrans back to SF
(or the other direction)
We did this a few years ago starting at San Jose, it was a lot of fun.
We added cable cars and the PCC cars in SF.
