This site began listing haunted houses in 2010. Before the site redo in 2010, I kept every previous year available to we could look back on what operated in previous years. I spent several hours tonight trying to get all of this data posted to this new site. Most of it I had, but I had to get one of the years from the Internet Wayback Machine 😉 (My old system I created was far better for archiving data than the modern and expensive one I use these days).
There is still a lot of cleanup to do, but I wanted to make this data available before Halloween. You can start with Year 2010 and take a look.
