I really suggest you do what you would normally do in an airport. Just look around. I was in SF
today actually. If you are willing to take the chance of leaving the airport the city has a bunch of cool stuff. BART is pricy (Orinda-Powell St.-Orinda=6.90) but if you jump on BART from SFO
and head to Powell St. you can snoop around the San Francisco Shopping Centre. It's a 29min. ride and will cost you $9.90 Round Trip. Lot's of cool shopping/food but if you leave the Mall watch your pocket, very tourest friendly so this brings pick-pocketers around all the time.
Getting to Pittsburg/Bay Point is impossible with your time. It's a 1hr 15min ride and will cost you $14.90 round trip. I live in Orinda which isn't too far past Powell St. so if your stuck feel free to stop in O-Town for a while. Not much here just coffee, house wifes, SUV
's, and a lot of "nothing to do" time.
The next suggestion which is even better is to get on BART and take it to Millbrae. It's a $3.00 Round Trip and will take 5min. Exit the station to Rollins Rd. Which is at the end and to the right of the bus stations at the bottom of the stairs apon exiting the station. Cross the street and contiue North East on East Millbrae Ave. you will have to cross the freeway (101) which you can only do on the right side of the freeway/street. They will be nice and stop just give it time. Continue for about 5 min. until the street ends. There's a great grassy area/park that is probably 100yrds from the 10R/L runways and is a great place to view departures.
Just do the same thing to find your way back to BART. The only thing is is that BART departs every 15-20 for the Millbrae-SFO
-Millbrae route. To get to Millbrae just take the Millbrae trian and to get to SFO
take the Pittsburg/Bay Point Train, it WILL stop at SFO
Again I'm always here if your out of ideas and seeing how Orinda has the name of Borinda I have a lot of time on my hands.
Hope this helps ya!
Thanks again and enjoy SFO
