Lloyd,
One of the biggest impediments to increasing participation amongst younger, married folks with children is the time to play.
The trend amongst younger family golfers is the need to tee off early and be home early.
Ergo, rounds have to take 3 to 3.5 hours in order to be able to fit family schedules.
Younger, married golfers want to tee off at 7 to 8 and be home by noon.
As a group, being younger means that they're more fit and capable of playing at a brisk pace.
The dilemma is that you can only fit 8 foursomes (32 golfers) between 7:00 and 8:00 at eight (
minute intervals.
So now some clubs tee off on both nines and increase the number to 16 foursomes (64 golfers).
The second dilemma occurs when both groups go to make the "turn".
If pace of play isn't brisk and equal on both nines, there will be a back up on the 10th tee and play on he back nine will be slower, disrupting the intended schedule.
Golf is much more than a sport, it's also a social event.
That combination is what makes it attractive.
But, if the current culture of slow play prevails, the social and sporting interest will wain.
Contributing to the dilemma is what Tom Doak mentioned, lengthy courses.
It seems reasonable to conclude that it will take longer to play/walk a 7,200 yard course versus a 6,500 yard course.
But, golf also has to retain it's inherent challenge.
How many have heard the phrase, in a derogatory sense, "it's a pitch and putt course" ?
So golfers, interesting breed that they are, tend to reject courses deemed "too easy"
So where's the balance ? What's the solution ?
From my perspective it's the marriage of interesting architecture, even quirky architecture on 6,500 yard courses, with a rollback in the ball along with 3:00 to 3:30 hour rounds.
Produce those results, and you'll "grow the game".
