My initial reaction to reading your post was 'If you buy a house next to a golf course you've got to expect the odd stray ball in your garden' but looking at the plan of the sixth at Wilmslow I'm a bit puzzled.

I agree totally with your basic premise, though. People buy houses overlooking golf courses because they get a nice view of rolling countryside. They then moan that there are golfers on it intruding on their little lives.
It reminds me of the idiot I once met who bought a house in late autumn backing on to fields. Come summer the place stank to high heaven - it turned out to be a pig farm! He petitioned to have the place closed down - only to be told in no uncertain terms by the council that the farm had been there breeding pigs since around 1650 and that perhaps he could have done some more research before buying the house...
