Transportation TIP the taxi's at SFO were cheaper than Uber ($9 vs $25) and the BART system was confusing resulting in me prepaying for a card with credit of $20. BART made me nervous in so many ways. I highly recommend using the TAXI to come and go to Portia's. Her place is a short walk north a few blocks to a brewery and authentic Mexican hole in the walls for a meal. Thanks, Portia, for the toothpaste.!
