I don't believe this subject has been presented here at Techimo before, so I figure I would do the honors.
I disconvered a new activity this past summer that allows me to geek out with technology while still managing to get some good exercise. As you guessed, this is activity is geocaching. Essentially, in Geocaching you use a GPS of your choosing to hunt down hidden "caches". The coordinates for each cache are listed at
the geocaching website (this is the biggest geocaching site, the others tend to be more regional in nature). You pop the coordinates in your GPS and go find the cache. The beauty of this is that there tens of thousands of these caches hidden around the country, all placed by fellow geocachers. When you find a cache, the idea is to take an item from it and then place an item. These items are no big deal usually, just dollar store items, although you sometimes find some more valuable items. You then sign the logbook and place the cahce back where you found it, to await the next geocacher.
The enjoyable part for me was the hunt, not the items. When a cache is well thought out, it can bring you to an area you did not know existed or hadn't been to in a while. Some are very difficult (there are one that require Scuba certification) and some are ridiculously easy, but most are at least a minor challenge.
Unfortunately for me, right when I was really starting to get into this activity, I went a blew out my ACL (blew it out playing basketball, should have been geocaching), so I am out of commission until next summer. I am hoping that I can live vicariously through others. Please let me know if you give this a try and let me know how the experience was for you. If you have any questions, I'll answer them.
Finally, this is an activity that relies on the goodwill of people. Please do not go find coordinates for a cache and then go destroy the cache (it happens). I do believe that the people of Techimo will enjoy this activity.
