Hide your temporary geocaches.
Walk around your neighborhood and find a place to hide your geocache.
It can be difficult to find a geocache in places where there are a lot of trees, because the trees obscure the GPS signal from satellites. So for a beginner using a GPS device, put your geocaches in places with open sky, such as in a meadow.
Once you find a hiding place, write down the coordinates from the GPS device. This is the clue you will give your geocachers. Coordinates always have a latitude and longitude.
