Ghost Video from Gettysburg PA

A couple of years ago, my brother and I went on a trip to Gettysburg, just before Halloween, and had the chance to go ghost hunting! We got some pics with some nice orbs, that were probably nothing more than dust on the camera lens! We didn't get to see anything like this! I believe this would be the Triangular Field that these people were filming, check it out!

Believe in ghosts or not, this is a bit creepy! It's almost Halloween, so I will try and find some more good vids and pics to post in the next month or so.
