From https://www.umass.edu/transportation/how-much-bus-fare:
Bus drivers will not collect fares/passes, but passengers are expected to have either a valid Five College student, faculty or staff ID cards or a fare ticket/pass for each ride.
From http://www.pvta.com/fares.php:
Bus Fares - When using cash, exact change is required.
Adults 13 and older - $1.50
$1.40 if purchased at the Customer Service Center.
The first source says that one has to buy some ticket in order to ride a bus and that bus drivers will not collect fares, but the second source implies that one can pay in cash. So can I use cash to ride a bus? Or do I need to buy a ticket at the Customer Service Center (if so, what's its location)?
