I have never been geocaching before so I went through the hide and seek a geocache feature online and added some to my watch list that are close and looked like fun, but when I opening up the intro app and true in the cache code (in this case GCJD6D) or the coordinates it won't find the geocache I want (titled Hidden Lake). If I type in the code it won't find it at all. I've tried it with a couple different ones and have had the same problem. Why won't it load the geocaches I want it to?
