I agree with most crushed stone. The blue driveway mix we use requires a light raking only once a season. This is only on the pads that have direct sunlight, which is maybe 7 pads. In the past 5 years I have had to apply maybe a yard and a half of mix. I could easily do concrete, but the blue stuff is better in so many ways for a private course. For a public course you would need someone to go through once a month, but it is easy work. You have to time it with the weather. Wait till its nice and dry. Rake and level the day before a rain. The rain will pack it down and it will turn to a hard surface in less than a couple hours.
