Hollow hallways

Walking around in Eastern State Penitentiary in Philadelphia, PA is somewhat eerie when you have it all to yourself.  There are numerous hallways, and they all echo with a hollow emptiness that you seem to feel deep in your gut.  I have heard that this place is haunted, and it is easy to believe when you visit here.  Apart from that - it's a great place to photograph!  Anytime you can capture some decay in HDR, it's all good and certainly worth any strange sensations you might experience there!  I did hear the sound of breaking glass - but it was me accidentally crushing my filter!  Oops!
