PITTSBURGH — Pittsburgh officials and those who control parking at the city's sports stadium lots are limiting tailgating hours in hopes of avoiding rowdy behavior and mountains of trash when country music star Jason Aldean performs at PNC Park on Saturday.

Tailgating will be limited to five hours before the 7 p.m. show, meaning stadium lots won't open until 2 p.m.

That move and others come in response to heaps of trash and scores of emergency calls at last month's Luke Bryan concert at Heinz Field.

The city will also use more police and Alco Parking Corp. says it will supply more portable restrooms — 200 — in hopes of keeping the lots clean.

Officials say the pre-event changes will be reviewed and may impact how the city polices tailgating before Pirates, Steelers and Penguins games as well.

PHILADELPHIA — Four ousted traffic court judges in Philadelphia have been convicted of lying to authorities but cleared of most charges in a sweeping ticket-fixing case.Two other judges and a businessman were acquitted in federal court Wednesday.The indictment last year portrayed the city's traffic court as a patronage pit, and said judges routinely fixed tickets for friends and allies. Several judges pleaded guilty before trial.
