Do not go to posted coordinates. They will take you to the middle of a stinky pond. This is a bonus cache for those completing the Haunted Evansville Tour adventure lab cache. At each of the 5 states, you will be given a code. Plug the numbers into this for the final coords: N A7 EC.C7A W 0C7 AA.DB0. The find itself should be very easy.
I thought this would be a fitting place for the bonus cache as this building has a resident ghost itself. The ghost is thought to be the spirit of a little girl who was killed crossing Virginia Street when this building was a school. I've witnessed things like doors opening after closed, doors not opening when tried, and unexplained noises. Some employees say she's mischievous.
I had to move cache due to construction. I updated puzzle as well.
