Bay Area Rapid Transit
Trains under and above ground in the SF bay area. They even go UNDER THE BAY.
Sort of ridic expensive.
A lot of people depend on them so when they strike or break down, everyone's fucked.
Lindsey: Let's all go to Berkeley tonight!!
Michelle: We can't all fit in your car though, and mine's in the shop!
Monique: I know, we'll take BART!
