mtngrl, I think there were a lot of folks that thought they could do it and changed their minds. It was pretty intense. The street experience almost more so than the haunted houses, in the houses you expected them to be around every corner. On the street you had no idea when you'd be followed, jumped at, growling in your face, etc. At one point I walked out of the stall in the bathroom into a pack of supposed convicts escaped from a women's prison, all of them brandishing chain saws. I washed my hands fairly fast LOL!
They recommend no one under 13 in the park for that night but there were quite a few families with small children, I didn't like that at all. My daughter wanted to go (she's always liked being scared and loves to scare also) but there is no way she would have had a good experience. Going through one house with a family in front of us with 2 kids probably around DD's age (7-8) and the people working intentionally scared the kids at every turn. They were pretty upset by the time it was over. I wanted to chew their parents, I'd bet good money they had nightmares.
Life is like a camera. Focus on what's important, Capture the good times, Develop from the negatives and if things don't work out, Take another shot.
