Yes, Headpro, I have a few without even having to think too much:
-- Follow the USGA pace-of-play guidelines to rate your course so you know how to manage it better, even slighgtly
-- Consult with your golf course architect on tee markers + pin position combinations, signage, etc.
-- On busy days require match play formats and educate golfers on how to close holes quickly dueing match play formats
-- Send golfers out so the pace does not seem slow (i.e., at regular intervals with realistic gaps)
-- Don;t let golfers hit on #1 tee until their time, regardless of whether golfers are clear
-- Mow roughs to avoid hunting parties
-- Create fun days where the course is set to executive-length and reduce rounds by 20% or more
Not all these will work all times at all locales. In fact, none will work if there is no buy-in by those in charge. But, ther are all ideas, and ideas are hard to kill.
