Pennsylvania casinos continue to thrive. Numbers released this week by the Pennsylvania Gaming Control Board show that over half-a-billion dollars in combined revenue was generated by the commonwealth’s gambling venues in July. The total includes over 79-million for Hollywood Casino at Penn National Race Course in Grantville, which led all casinos in the state. Hollywood Casino York reported more than nine-million-dollars in revenue, an increase of more than 15-percent from last year.
