Trivia

Pennsylvania has the largest rural population in the United States.

On the map, Pennsylvania is a torn rectangle with a ragged eastern border. If you ran your hand over a surface map of the state you would feel a wide range of textures -- smooth coastal lowlands around Philadelphia and Erie; spiny ridges and clefts in Central Pennsylvania; rocky plateaus rising in the western and northern portions of the state; and the scratch of Pennsylvania forests scattered through more than half of the Commonwealth.

Although the average climate of Pennsylvania is usually described as 70 F in summer and 30 F in winter, a true average climate for the state does not exist. This is because Pennsylvania actually has five temperature zones from the Maryland border north to Canada via Lake Erie. So the average temperature in one part of the state may be considered an extreme a few mountains and valleys away.
