There are different types of caches. The first one I found was a "virtual cache". In this type there is no physical cache, but the coordinates lead to an interesting or historical object. To get credit for finding the cache, one must email the answer to a question to the person who made the cache in order to prove it was really found.
There are regular caches where the cache is an ammo box, gallon tupperware container, or something of that size. There are mini caches where there is a log book and very little room for anything else. There are "micro" caches where the cache may be the size of a pill vial with only a small log book in it.
Some have been very easy to find, and others have been either hard to find due to ingenious hiding or hard to find because of difficult terrain.
The GPS I have is a Garmin ETrex Vista and it has functioned well for geocaching and it's kind of fun to play with on trips.
The premise of the cache was that back in the 60's a rich lady was found dismembered in a wooded area in north OKC. Her little dog was never found, and neither was her fabulous diamond necklace. The hint for the cache was to look for the sparkling diamonds and follow the blood trail to the head.
When we found the coordinates we shined our flashligts into a wooded area and saw a reflective dot on a tree. We followed the dots from one tree to another deeper into the woods until they led us to an abandoned old house. At the house blood (red paint) had been smeared in places to lead through the house. Finally in the bathroom (head...get it?) we found the severed head of the woman (a styrofoam head used to display wigs) with her hair and the log book in the base of the skull. Her dog was lying on the floor (I'm not sure if it was a real mummified dog or a model but it looked real enough I wasn't gonna mess with it. It being halloween and dark and spooky made this a really fun cache to find. We were glad we were all together.
