Gary,
Try Twin Grove c/g in Pine Grove, PA. It is near Harrisburg and will be close to half way.
My wife and I are from the WNY area (south of Buffalo). We travel between southern MD and WNY frequently. Know the route very well.
We have stayed at this c/g a few years ago...and really enjoyed it. Looks like it might be improved.
Check it out.
good luck,
Mike
