Hi! What are some examples of how Latitude and Longitude are used in an every day situation? I can see where an airplane pilot would use this but why is this on our gps units? I am fascinated simply because I would like to come on the geocaching trip in September to Maine and would like to know a little more about how to apply this part of the gps because I have a feeling we just might be given some clues using this branch of the gps. Thanks. Mary Ellen Earls Remember! Today is the Tomorrow you thought about yesterday.
