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.
After all, on most every other golf course the longest holes are normally in the mid-500-yard range, with a par of 5. One guy from a golf magazine flew in for a round and suggested the par 6 be turned into two shorter par 4s. But Farmer isn't budging.
