The city is offering a convenient way of getting to the Aloha Stadium for Sunday's NFL Pro Bowl.  It's the Football Express, a shuttle service run by TheBus.   At least 50 air-conditioned buses will pick up fans from neighborhoods across Oahu and drive straight to stadium gates. The cost of service, one way, would be $6.25. Since FootballExpress is not a regular bus service, bus passes and transfers will not be accepted. For more information, and to find out where you can catch the Football Express shuttle near you, call 848-5555 or log onto Kickoff time is 2 p.m.
