On Wednesday Amara, Ben, Emily and I went geocaching in the wilderness of Charleswood.

Geocaching is a "sport" where people hide containers in parks and other places and place the coordinates of the containers online. Other people then download the coordinates and use GPS receivers to attempt to locate the containers and sign an enclosed guest book. Some containers have small toys which you can exchange assuming you had the presence of mind to bring one with you when you left.

To make this extra nerdy, we used my home built GPS receiver. We set out with the locations of four caches written down and managed to locate two of them. We didn't spend much time looking at each location due to an abundance of mosquitoes, but managed to find the easier caches.

I enjoyed the hunt and would definitely like to go geocaching again. If you want to learn more about geocaching, I recommend you visit http://www.geocaching.com which has excellent explanations and a huge databases of caches waiting to be found.
