Brent,
Golf numbers are down even at municipal courses. When you see a 10%-20% reduction in rounds, you are talking some real moeny. Why WOULDN'T they want to attract new golfers? The revenue stream generated from muni's often goes into the general fund and pays for programs that might otherwise have to be eliminated.
For example, where I live the local University course, a 9 holer that is no great shakes, generates $78,000 free and clear for the University. That kind of money coming into a local government can fund after school programs, another cop, a city planner, free summer swim programs, etc. etc. Would these golf course owners rather pay higher taxes for community programs, or eliminate this source of revenue?
My experience has been muni's compete fair and square with private courses. Many pay there own way and rely on little if any taxpayer support. They do not cost any less to maintain, and they generally charge a similar fee for play.
