W elcome to Gridville, the cute little burg shown in Figure 3-1. You and I are going to pay this town
a quick visit because it looks like a great locale to review basic concepts of location, plus latitude and
longitude, the topics of this chapter. I say “review” because if you are like most people, then you prob-
ably learned about these things during elementary or junior-high school, but may have forgotten some
or most of it later on.
Knowledge of latitude and longitude gives you basic location and orientation skills regarding our plan-
et Earth. It also affords the opportunity to learn all sorts of little tidbits, which, in addition to impress-
ing your friends, can greatly enhance your understanding of geography.
