Phone calls and visits to local Wawas in the "Central" areas of the state gave us this map:

The Red Counties represent those with Wawas that ALL sell the book.
The Blue Counties represent those that do not have any Wawas.
The Blank Counties have been singled out.
A "P" means that the Wawa had the book.
The "N" means that the Wawa didn't sell the book.
Two in disputed territories say that they had the book, but that it sold out.
