Abbreviation for Pittsburgh Area Transit, also known as PATransit officially. It is run by the Port Authority, and consists of dozens of bus routes and a small light-rail network known as "The T." (For those of you from Boston, rest assured that the logo for Pittsburgh's "T" is very similar to that used in Boston.)
Students of the University of Pittsburgh and Carnegie Mellon University pay $28.00 per semester for a sticker on their ID cards that entitles them to unlimited rides on the entire PAT system. This is good, considering that it can take you the country mile from Oakland to the airport, normally a $1.95 fare, for nothing. Unfortunately, as in many cities, the T and bus routes stop running after around 1:00 AM, leaving many partygoers and other night owls at the mercy of the Pittsburgh taxi duopoly.
