On the way to Pittsburgh stopped at the Pennsylvania Travel Center along 79 North in Whiteley Township for info.
While not manned at the time of visit a wealth of items to enhance your visit was available.
The Center was clean, organized and worth the stop.
In my visits statewide have always found these areas worth the time to investigate.
And it gives one time to stretch legs, get a breath of fresh air, enjoy nature and take in monuments or art work indigenous to the State.
