I went to a ghost hunting event at the J. Rollins School in Lawrence. I did not capture much, due to the large number of people and the general loudness of the place, but the building was cool to investigate. It was built in 1892. The library (in the basement) and the clock tower are two of the more known haunted areas.
We were using the ghostbox. One woman asked if the security guard was there with us. We all heard two loud bangs on the outside of the closed door, and then the ghostbox replied "You need to open the door".
Do you like the kids here? Two "yes" answers. The funny thing is, everyone was expecting the answer to be "no", so that is what they heard.
Extracted, just the answer. You can hear two different voices saying "yes". One is an adult woman, the other a child.
"Here". The first one I got at the school, before the hunt started. They had scary music playing, which you hear at the beginning.
"We're heeeeeere". Heard behind the Principal's voice, who was telling us the history of the building.
Again during the intro. There were NO CHILDREN at this event. Everyone was sitting and listening to the intro. Pretty loud, huh?
