Brian, do you really want two southbound legs? Also, What do you
mean by the phrase "in that direction for one mile" for the 2nd
leg? Do you mean a) along a geodesically straight path, b) always
going due East, c) along a Euclideanly straight path, d) something
else? Do you want the problem performed on the Earth's surface?
