This Saturday will be 90 degrees in Philadelphia, so what are your plans? If you haven't made any yet, let PennDesign make them for you! Head over to The Eastern State Penitentiary's annual Bastille Day Festival. The penitentiary is teaming up with The Bearded Ladies for a fun-packed hour long presentation of the French Revolution with music, dance, beheading and raining Tastykakes. If that doesn't sound fun enough, it's all FREE!
