Cool. My daughter started working in one at about 9 years old. She is a horror film fan.
My wife and I used to help build, run and act in haunted houses.
Look them up online and try to talk to people that have been to them.
Mine wants to see some horror films, but we don't think she's quite ready... she got scared watching Coraline a few years ago. It's not really horror but a thriller, but we think she might be ready for Sixth Sense though
