The Tribune (a Mellon-Scaife paper) is so intent on getting a wider audience that it calls it Jack's Run Creek.

All of us locals (including this transplant) simply call it Jack's Run. Every yinzer in the vicinity of the 'burgh calls them runs That's why we have Campbell's Run Road out by the airport. It ain't Campbell's Run Creek Road. Weird, just weird.

I lived 12 years in Columbia, MD. The neighborhood is officially know as Long Run. There is a greenbelt all along the stream known as Long Run, with a bike trail built along it’s entire 5 or 6 mile length (is that long enough to merit the name Long?). I walked it many times.

That part of Maryland, at least, also calls them run.
