From what I have been able to find the house was never finished, maybe only partially framed.  Tom donated the property to a local community college who used it for some horticulture classes and after a few years I think the college tried selling the property but I don't know if it sold or not.  We farm within a mile or so of the property and there is an old sign along the road that say's "Property of Indian Hills Community College".  I have never driven around to see if what's left of the house is visable from the road, on Google maps I don't see what looks like a partial building site in the area but it's possible the college demolished the house. 

If you go straight south of Batavia on Ash avenue I am pretty sure their property is on the west side of Ash between 260th and 270th avenue and depending on the news reports it was 1,300 or 1,600 acres.  My dad was at the auction where somebody who was working for them bought one of the farms and the guy just stood over to the side holding his thumb up until the bidding stopped.
