I've taken the bus before, but not this particular one. The schedule says that I have to pay for another zone each time I cross a zone boundary. From looking at the map I've determined that I'm going to cross the zone boundary. How do they collect the money from you? Am I going to have to get off and onto another bus? If I do pay for 2 zones instead of 1 upfront, how do they know people aren't paying for 1 zone when they're really riding for 2? I'm confused =/
