Hi Tom,
 Sorry about that, didn't describe them very well. The 'circles' are not
perfect, but generally have a circular freeform shape. It almost perfectly
matches the pattern of the limbs on the oak tree, just 5 feet beyond the
drip line. Stretched wider where branches are longer, and indented a bit
where branches are shorter.
 The dead grass is consistently almost 6 inches wide, and nearly
continuous. Just a few tiny breaks here and there.
 The horse chestnut in the backyard has an almost perfect circle. My father
in law's next door neighbors told him it would be there in the summer. They
said this in March, when my inlaws moved into the house.
 It is unlikely that it has anything to do with fertilizer, at least not
applied in the past 3 years. The original owners kept a meticulous yard,
But the people who lived there most recently only went outdoors to get to
their car.

 I'll try and get 2 pictures of them and put them on my website. It will
take at least a week.
