I was riding through Mellon Park last night and noticed a couple of things people should be aware of. First, when you enter the trail at the back of the basketball courts from the Fifth Avenue Side, after a short time you reach a T junction at the construction fence. The left side of the T leads to a locked gate, i.e., a blind alley, at the parking lot to some apartments. That should be signed, but isn’t. And if you follow the detour around to the right and then follow the sign marking the path to Shadyside the path is fenced on both sides, and somewhat isolated. It seems like a pretty good place to get mugged, since there’s no way to turn around and run.
