RE: PA opener advice
It will be past peak, but I'm sure a few bucks will still be exhibiting rutting behavior.
Calls, scents and any other thing resembling trying to use a deer's natural behavior or movements are out the door after the 1st 30 minutes of the season in my neck of the woods. After that it is merely hope you are on the right escape routes as they get pushed around all day.
If you are in a remote and unpressured area, or catch a still aggressive buck that hasn't been spooked out of his mind yet calls may work. Scents I wouldn't bother with, as I don't think they would offer any sort of an advantage.
