Port Authority spokesman Jim Ritchie says the morning commuter has been exceptionally quiet due to low ridership.

However, KDKA producer Aaron Inver gave up on the bus for his commute. He jumped off the bus rather than sitting through the checkpoint delays near Fifth Avenue.  Buses are stacking a bit at the entry points but we are hearing of no significant problems once they clear through. 

That's a great reminder that you can walk and bike anywhere your heart desires downtown without police interference.  However, you are still required to clear metal detectors near the security perimeter around the Convention Center.
