The Knoll is a terrific par 70 Banks golf course.
You won't be disappointed.
Steve,
I think charities that allow 36 foursomes make a mistake in that those events usually turn into 6 hour rounds.
While the first year may be successful, many golfers pass on subsequent years due to the experience.
If you can arrange for 18 foursomes in the morning and 18 foursomes in the afternoon, the rounds are cut down to 4.5 hours and everybody enjoys themselves and you get repeat play in succeeding years.
Good luck.
