Don,
I know the WKU and R&W went out of Possum Ridge, so I doubt it would be anyone from those. I do believe the route 31 and EKU Events were the one going out of that area, but those were on Sunday and I do not know if any went out on Saturday. I thought this might give you a starting point on at least some small level as to "Who" might have lost it. Wish I had more for you but I was at the Possum both days. Hope you find the owner my friend.
