We had to get creative, split up our already small group of true investigators (5) and take the board member's group to another area to "investigate."
Little did they know that while the were being occupied elsewhere we were able to gather some evidence in 2 key areas of the museum. But, by the time we got our entire team into the room where the activity had appeared, it seemed to have left.
So, we are left with a lot of personal experiences and not a lot to back it up.
