First problem today

This app has been a godsend on long trips. Today we needed a pit stop and took the Camp Horne Rd off I 279 south toward Pittsburgh. There were supposed to be amenities .2 mi away but getting there wasnt well marked and the roads were barrow, windy and hilly. We had to go onto another road and up a big hill to a shopping center.
Otherwise a wonderful help normally.
