SF was one quiet city on our last day. Not much happened - spoke to a homeless person named Mary for about an hour and then had some cheese and wine back at our hostel (it was free). Played some pool and went to a bar down the street that had THE BEST mango mojito! I'm definitely introducing this to friends back home. Stayed 'til closing hours then went straight to bed.
Up early for our 10:50am flight to San Diego. We caught the BART (Bay Area ? ?) to the airport, but timed it very badly because we missed our flight!!!!!!! Luckily we were put on standby and given tickets for the afternoon flight (4:20pm) at no extra cost - there's barely anyone on this flight so we are guaranteed a seat. I am so grateful for that - and now I can breathe a sigh of relief.
