Sproul....Yes, the bar and restaurant is still up and running in Medix Run. Has hotel rooms, too. Good area to see elk in, also.
As far as Wycoff Run area, it's actually a pretty good distance from Medix Run. You gotta get on the Quehanna Highway at Medix and head up over the mountain towards Karthaus. I can't remember if it's on the Medix side or the Karthaus side of the old "Boot Camp" prison area, but a big sign along the road will show you where to turn left. You will eventually come out down near Sinnemahoning. You have probably been in the "Willows" there, too.....
