Pennsylvania - Considering the Declaration of Independence was signed in Philadelphia back in 1775, it’s easy to understand why Pennsylvania has been newly nicknamed as the “State of Independence.” Beyond its rich, political history, Pennsylvania offers an assortment of extreme sports, natural wonders and national events, such as the Groundhog’s Day shadow watching in Punxsutawney. Spelunkers in Allentown and Reading stash their ropes, helmets, and other hiking equipment in mini storage units before taking a guided tour of the famous Crystal Cave near Kutztown. While Pittsburgh is a bustling metropolitan area, residents still need self storage facilities for their snowboards and skis after they finish gliding down the slopes at nearby Boyce Park Ski Area. Once the site of the biggest battle during the Civil War, Gettysburg attracts history buffs and reenactment fanatics who rent mini storage units for their antique uniforms, firearms and battlefield relics. Pennsylvania has hundreds of self storage facilities located in communities across the state.
