This house is for sale down near Northfield, Minnesota. It has an 8 car heated garage on 5 acres -- and it's round. Looking at the pictures, I am pretty sure you could take laps around the inside edge of it.
What's amazing is that the taxes shown for 2009 are based on an assessed value of $1.5 million. It's selling today for $315k and owned by a bank. I am pretty sure they'd take $299k if you asked real nice.
