Here is the link to the main Geo site. Geocaching - The Official Global GPS Cache Hunt Site Me and my oldest son have been Geoing for 3 years and we have a blast, it's a great way to get out of the house and spend time with the kid. We have found things from Geo Bugs, Hot wheels, and small things plus the I found it book, then we leave things in the cache too. We leave comic book goodies, and geo coins in them when we find them. If you are going to do this it is recommended that you put something in the cache after taking something, but you don't have to take anything from it if you don't want to. Just make sure to fill out the found it log, and then when you get home you post your findings plus coordinates to any caches you make and put in places. We have over 30 that we have put out and we have found over 500 across the NS and SC areas.
