Well, since you mention Johnstown, I see that there is a Ukrainian Orthodox Church in the area, Sts. Peter and Paul Parish. I'm assuming they probably worship on the old calendar, perhaps you could check to see.
EDIT: Oops, I found out there's another Sts. Peter and Paul UOC in Bakerton-Elmora, wasn't that the area that you wanted? Check to see their schedule, too, whilst you're at it.
Here's the directory in which I'm finding this from, anyway:
