Sassafras root is still used to flavor traditional root beer, although since sassafras was banned by the U.S. Food and Drug Administration because of the carcinogenicity of its constituent safrole, most commercial recipes do not contain sassafras. Some commercial root beers do use a safrole-free sassafras extract.
There are usually 18 holes in a golf course; some have 9 holes or some multiplier of 9 holes. I have played at golf clubs with 9, 18, 27 and 36 holes. However, a standard round of golf at most golf clubs / courses involves 18 holes.
If you are thinking about building a par 3 golf course, here are some frequently asked questions on the subject? HOW MUCH LAND IS NEEDED FOR A PAR 3 COURSE? At least 30 acres (12 hectares) is required for nine holes of similar length to the par 3 holes on most courses with a par of 70 to 72. Extreme contours, land features that must be avoided like wetlands or boundaries restricting full use of a site for holes can demand somewhat more land.
