by Fred J. Calfior and Douglas W. Miller

*“True or False! The shortest distance between any two points is a straight line. No matter what your math teacher said, or sociology teacher said, it's not always true! It was true until Christopher Columbus' discovery that he didn 't fall off the edge of the world, making it therefore round! The circles whose planes run through the center of the Earth are known as great circles. These are of special significance to a navigator, such as yourself You just don't know it yet! An arc of a great circle represents the shortest distance between any two points on the earth's surface connected by that arc.”*

1) Turn towards “**SUNOL GOLF COURSE**”

2) Place *the* numbers **4, 5, 6, 7, 8, 9** along the sides of the triangle below, using each number only once, such that the numbers along **each** side (including the given numbers **1, 2,** and **3**) add to **17**.

Take the sum of the 4 newly added numbers on the left side and the bottom side of the triangle, and mosey over to that **AirLeg!**
