The next day after the graduation was kind of needing a getaway (from my family) so i decided to take the Bart out of Pittsburgh into the city. Had never been on the Bart and thought it would be kind of fun to explore San Francisco. Drove to the Bart station from the hotel and parked the car . The station is kind of confusing if you have never been to it before . They provided parking and such. However you had to pay a dollar to park there for the day. Wasn't sure how to do this (guess you had to jot down your spot and pay somewhere). When i got to the station, there was a gentleman in the booth who i asked. He told me didn't have to pay on Sunday which was a relief . .However the actual ticket itself was all self serve and extremely confusing if you have never been on the Bart . Anyway put my credit card in payed $20.00 (think actually i only had to pay $11.00) but i was in a rush to catch the train and asked someone later about it . Apparently if you have credit on the ticket, you can use it at a later time (till it expires) anyway gave the ticket to my brother's ex-wife, she lives up there and could get some use out of it...
