We had a view of his house from our kitchen window in the place we stayed in Canyon Sands this winter. I was interested to learn that it was designed to look like a volcano. Everyone refers to it as "the turtle house" because that's what it looks like from afar. We thought we'd drive up there one day because there look to be a number of interesting houses in the area but our neighbours said they had guards who wouldn't let you drive up very far.
