Geocaching - Treasure hunting with a GPS
GPS - Global Positioning System
On nice days my buddy Ed and I go looking for geocaches. It's fun and a way to get some exercise. I check the www.geocaching.com web site for the location of geocaches close by. It gives among other things the Latitude and Longitude accurate to with in 10 feet and a hint. I check www.mapquest.com to get a map of the general location. We drive there by car. When we park as close as we can we start hiking. I have a Garmin GPSmap 60CS unit that points the way.
Here are some links to help you get started.
