I accidentally caught 'orbs' on a haunted tour of the underground tunnels in Portland, Oregon. I have heard of them but never paid much attention to it until I looked at what I had on film. I did some research online and found that there was quite a bit of orb activity, and read arguments pro and con.
Most of my research has been related to Mars anomalies, but this has caught my interest and I'm going to do my own study and research into it.
