Wildlife Prairie State Park transformed into Wildlife Scary Park.
It's been a central Illinois tradition for more than 20 years.
You can come dressed in your favorite costume and go for a haunted ride on the "train-sylvania" express.
There's also food at "franks-n-steins" and Halloween gifts at the "boo-tique."
And don't forget about trick-or-treating in the "ghoul-y-whopper" subdivision
"They can go and knock on the doors in the gollywhopper area and get candy at each door, just as if they were going through the neighborhood, but with a lot less walking," said W.P.S.P. Executive Director Jason Boerger.
Scary park is going on for two weekends in October. Your next chance to attend is Oct. 26-28 from 5 p.m. to 9 p.m.
