Abandoned haunted locations

Hi everyone, this is my first post. I am coming over to the US for the first time to investigate haunted locations, and I am super excited, and I can't wait to get there. I was wondering if any of you had some recommendations for any abandoned haunted locations. Thank you for your time reading this post

I found quite of few locations in my state (ohio) on Haunting.org - Its a newer Paranormal Database that allows researchers such as myself to post evidence, and information regarding a haunted location. Might be worth taking a look. I know Molly Stark Santorium was posted on it a known abandoned haunted location.
