My friends and I decided this would be a great way to spend some free time this summer. We joined some sites, watched videos, read tutorials, got the right apps for our Android and iPhones, and still, we have yet to find a single cache. We can find the coordinates on our phones, we decode the hints and we know we're in the right place but we must be missing something. We can't find the cache itself. I know the type of containers and hiding places to expect from watching videos but still no luck. Can anyone give us any advice?? Why aren't we having any luck? 5 different sites and several hours. Nothing.
