Kennywood appears to be testing the resale market waters by listing their Intamin freefall, named Pittfall, for sale through International Rides Management. The ride first opened in 1997 and stands an impressive 251' tall, offering some amazing views of the landscape around the park.
According to this article, Kennywood isn't totally set on removing the ride yet, though a representative from IRM seems to know what ride they're shopping for as a replacement. Despite those conflicting views, the ride was listed on IRM's Facebook last week.
While Pittfall is a great ride and I'd hate to see it go, the possibilities of a replacement are wide open with the selection of tower thrill rides available today. Personally, I'm still waiting for that makeover of the Old Mill the park had planned!
