Not a stupid question at all. It usually depends on how many people in your party. There aren't many courses left that I shoot, where you have a trapper. Anyway My crew would usually go $5.00 per man, if the trapper was really working hard for us, we may even go as high as $10.00.
Or you can go to a SC place that lets you throw your own. Don't have a lot of experience with either of them, but I know what I like and I don't like the SC places where someone leads youthrough the course and throws for you.
