Over the last 4-5 weeks my rectangular, suburbian, lawn has been badly
deteriorating in the four corners. It'd been in place on a new estate
since May 2005 when we moved in; didn't have the same problems last winter,
and has been looked after by me.

The grass has gone really thin in a triangular area in each corner, and I
can see a lot of little mud spirals on the surface instead. The areas
affected are visibly growing each week.

I know that our whole estate suffers from leather-jackets, but from what I
read about that, this is the wrong time of year to see a problem from that.

On three of the four cormers, there is either a brick wall or 6' fence
abbutting the grass.
