@AJs:
It's been a very long time since I read The Wizard of Oz. Is Wichita where the story starts?
I googled "Dorothy's House Wichita" and nothing came up except ways to get to Liberal. That's where the house is that is advertised all over Kansas as THE Dorothy's House. From what I understand (and I have been wrong before…it could happen again) the house in Liberal is where they did some of the filming.
But I love the Witch-ita reference...:D
I think Dorthy's house was just considered to be a farm house "out in the middle of nowhere".
