Your GPS will lead you to an area ("ground zero" or "GZ") where there is an obvious interesting object ("beacon") for a hide there. The cache container you are looking for is an aluminum cylinder about the size of your thumb called a "bison" by geocachers.
The cache might not be in the first place you check, but you might find places that you cannot check without some tool (a "tool of the trade" or "TOTT"). You might want to carry with you a few tools for geocaching that commonly come in handy. At this cache, even if you don't have the proper tool, you can probably improvise something that will help you out. Perhaps experienced geocachers can list in their log entry a"tool of the trade" they carry around to inform beginners.
One important part of geocaching is to replace the cache the way you found it after signing your name. The hardest part is often getting the paper log back into the container. The trick on "bison" containers is to roll up the log and insert it into the cap first, because it is the smallest part of the container. Then the container can be screwed together easily with the log inside, and the next finder can easily remove it.
*** Please include in your log entry any suggestions and tips you have for beginners. ***
