Pen Mar Park is a scenic area located on High Rock Road on the Mason-Dixon line in Washington County, Md, (not far from Blue Ridge Summit.) "In 1877 the site was opened as an amusement park by the Western Maryland Railroad. It was dismantled in 1943. The park contained a roller coaster, carousel, miniature train and railroad station, dining hall to seat 450 people, and a dance pavilion" - Wikipedia. There was usually a breeze flowing over the mountain ridge and plenty of shade from deciduous trees throughout the park.

For residents of Bonneauville, the park was a desirable mini-vacation destination. It was a treat for Bonneauville families to be able to take the train from Gettysburg to Pen Mar park on a Saturday or Sunday. It was a social event worthy of newspaper mentioning.
