"Walk the halls of Chicago's most notorious killers" Aaaaaaaaaaand that's gonna be a hard no for me. Absolutely not. Haunted houses are one thing, converting an old warehouse space or sports complex or barn, etc. to scare people is fine, sure. What's not okay is having people scare you in an ACTUAL ABANDONED PRISON. People died here. Literally. Criminals walked those halls. And now you're gonna have a bunch of teenagers dress up as monsters to scare people because they need a little side cash to afford their tux/dress for homecoming? This is one step shy of dancing on random graves in a cemetery... I believe in ghosts and I do NOT need the spirits of murderers and other criminals adding me to their list of people to haunt in 2018. No thanks.
