Geocaching

One of my hobbies that I have done for a while is geocaching. I mentioned this to some friends the other day, and I was surprised they had never heard of it, so I figured it was a subject worth a post.

Geocaching is basically a high-tech treasure hunt. People all over the world are hiding small waterproof containers and then posting the GPS coordinates on web sites like geocaching.com. You can go to the site, enter your zip code, and get a list of hidden caches near you. You will be amazed how many there are (right now there are 6,540 within a 50 mile radius of my house). Using a GPS receiver (can be purchased for about a 100 bucks) you can follow the coordinates and hunt for the hidden treasure. Most caches contain a log book to sign, and many have little trinkets that you can take - as long as you put something of yours in to replace it.

It was started in May 2000 by Dave Ulmer in Oregon and has spread rapidly - there are currently over 317,000 caches around the world. One of the things I like about it is that it helps me find interesting places that I probably would never have seen. Most caches are placed in a site that has some kind of intrinsic value. It might be a beautiful view, or a hidden stream, or historical interest, but there is usually something worthwhile about the location other than the hidden cache. It's a great combination of mystery, exercise and geekiness.

A lot more information can be found (as always) on the Wikipedia page.
