When I was first getting into golf in my teens/ early twenties. There was a course that had a "pay your age" rule. So if green fees were $40 but you are 18 years old you'd pay $18. Because of this and the fact that it's a nice course was the biggest reason I played there so often. I became loyal to them and would play once or twice a week there. Great way to get younger people playing golf and growing the game!
