In Sioux City to get yourself in the mood for Halloween you need to head downtown. There is "Nightmare on 4th Street" and "Fear Factory". Both are located at the same place on historic 4th Street. Tickets are available at the door. Admission is $8.00 per person. Save $3.00 when you buy a combo pack which gets you into both.
I went last year and I screamed the whole time. I went through "Nightmare on 4th" and this year I will go through "Fear Factory". Oh!!! don't go by yourself.
