Do you believe in Ghosts?

So out of curiosity my friends and I went ghost hunting to a nearby bridge not far from work Saturday night. After reading stories about this bridge being haunted we thought why not see for ourselves. After arriving Saturday right at dusk it didn't seem scary as we thought. After while a few teenagers showed up too but we never did hear anything or really see anything except in our cameras. What a fun adventure and eerie at the same time. You can see some of the orbs I caught on my pictures but my one friend got some really cool pictures. Do you believe in ghosts?
