Hundreds of pet owners and others attended an open house Saturday at the new Sunbury Pet Animal Hospital, located in a rustic setting on Route 890 in Rockefeller Township near Augustaville. Tours of the facility were conducted, free food, balloons and T-shirts were given and free rides on a replica of an old-west-stagecoch were offered. The facility is one of the most expansive and modern veternarian hospital and boarding centers for pets in this section of Pennsylvania.
