I didn't hear any comments about BART or buses at all today, listening to the AM stations. I couldn't get the San Franciso Chronicle online, either, since probably everyone was going to the website for info on detours around the closed-down areas of the freeway.
It was an unusual day for traffic. Lots of people apparently stayed home, not wanting to deal with the uncertainty. Tomorrow will probably be a better indicator of trends, including use of BART.
