I don't live anywhere near there, but I was lucky enough in the general area in October a few times, so I have been to this haunted house twice. It can be difficult to find the place, and it can be a long wait once you get there, but it isn't a long wait for nothing. It takes me most of an hour to get through the thing. I hate to spend my money and wait in a long line for a haunted house that only takes ten or fifteen minutes.
Be warned if you have a fear of heights or just don't like giant slides. There are a lot of stairs, sometimes you get from one room to another on a slide, and at the end you get out of the place by sliding down like four stories. The last slide can be avoided if you say something ahead of time, but I'm not sure about the smaller ones.
This same company also has The Edge of Hell, and a while back they bought two more haunted houses from the competition. They are all in the same warehouse area. If you manage to find one you aren't far from the others.
