I am still very new to the idea of geocaching, but so far I think I'm a big failure at it. I've tried to find two different caches, both rated as "easy" and very close to my home. Both times I wound up with nothing, even though (according to the geocaching website) other people have no problem finding them.
Example: since I don't have a GPS at the moment, I downloaded a free intro geocaching app from geocacing.com. It showed me the location of the cache on a street map. It was at the very end of a certain street. At the end of that street was a small paved area on the edge of an embankment. with trees around. The cache description and hint said not to go over the embankment, and that the cache was at chest height. Well, my partner and I searched every tree and bush that was at chest height, and we didn't go over the embankment, and we found nothing. Nada. Zip. Yet when we checked on the geocaching website, it said that someone had indeed found it today before I went looking, so it must be there somewhere! All the comments on the site said "Easy! Supremely easy! Easiest cache I ever found! Supremely easy!" and things like that.
Now, my eyesight isn't exactly 20/20, but my partner has pretty good eyesight, and all the comments made it sound as if the cache was likely to jump up and smack you in the face as soon as you got anywhere near it.
We also tried a different cache with a GPS, also rated easy, and just as with this one today, absolutely no luck no matter how hard and long we searched. In fact, we tried twice, and still no luck, even though there were plenty of comments from other people who found it.
So with or without GPS, it seems my partner and I must be missing something really essential if neither of us can find something that is supposedly so ridiculously easy to find.
