Imagine finding a hidden tunnel in your house? Would you think that's scary or cool? One guy in Illinois was fixing up his sidewalk when he realized that he actually had a secret mystery hidden under his home ... a very well constructed tunnel.
For now, there are only assumptions that the tunnel was made as part of the underground railroad but no one really knows. One thing that is for sure is that it's probably got a decent history behind it and maybe even some secrets to uncover.
If any house was to have ghosts ... I bet it would be this one. Just saying.
