CGCS and Dave,
I'm not so sure that I would greet the sounds of mowers at 5:30 am or 6:00 am every Saturday, Sunday, and Holiday with the same enthusiasm and understanding that you proclaim.
Since some posters on this site hide their participation from their spouses, I wonder if those same spouses share your views on disturbing their households at those hours on weekends and holidays, especially when the kids were sleeping so soundly.
The reality is: a cushman or equivalent gas powered vehicle pulls up, the mower is downloaded, the green is mowed, the mower is uploaded, the cushman drives away. Or the triplex drives up, mows the green, then drives off.
It is also not unusual that more than one green is in the area in question.
Let's not be so quick to think everything a golf club does is correct, and that everybody else is wrong.
Prudent activity combined with good proactive community relations can sometimes solve a problem when the club doesn't have a leg to stand on.
P.S. Most golf courses aren't located at the end of the runway at O'Hare, and the mower noise rises above all others.
But, that's just my opinion, Tom Paul can still be wrong.
