Did you know that . . .

. . . you can figure out the trajectory your irons are supposed to have by stepping on the head and looking at the angle the shaft has? As you can see below, Sandi, in the foreground, is stepping on a sand wedge and Barb, behind, is using a 6 iron.

So when would this bit of trivia be useful? If you need to hit over or under a tree or bush, it would help to know how high or low the ball should start out.
