No intention to thread-jump, but the direction of this one allows me to bring up a program I've wondered about for years:
Imagine that you are a high-end, public course, and you want to improve your greens. Your play comes from people who don't consider the club "home," so they don't take great care of it, especially ball marks on greens.
My proposal: bring in 20 local kids 2 times each week. Have them work from 7 pm to 8 pm, in groups of 4-5. Each group is responsible for 3 greens, and they need to repair all divot marks. 3 older kids (foremen) drive a third of the course at 8 pm, making notes on which greens are satisfactory and which are not; or, the superintendent does it the following day.
In exchange for the work, each kid gets a walking round of golf at an off-peak time. The club promotes proper golf course attention and kids who might not normally play that course, get to play it. Working from 7-8 does not preclude having another job (like caddie) at another establishment.
This should work, in my mind. What reason would we have for not doing it?
