I went out to make my first attempt at geocaching today with the groundspeak software in my iPhone 3G. On their web site some people say that's all you need and other people use it just to locate a cache and then they put the coordinates into a GPS. I was looking for one that is supposed to be easy and as we got closer and I zoomed in on my screen it looked like we were right next to it. So we looked around the bush near us and didn't see anything. Then the app screen started jumping around so suddenly it was locating us outside of town and then we'd be back where we were. It was strange but it made me lose confidence in using the software. Maybe if I knew more what I was doing, it would help! javascript:emoticon('')
