These photos were taken after a tornado destroyed a neighbor's
machine shed and grain bins near Stichnoth World Farm
Headquarters near Stockland, Illinois.

The final scenes of Twister, where Helen Hunt and Bill Paxton find
themselves in the midst of an EF-5 tornado and strap themselves to

of Eldora, Iowa.  The big white farmhouse is located a couple miles

House Movie Site Bed & Breakfast-RV Park.
It appears the park is no
longer in operation.
