I just found out today that there was a basic, but very good, article explaining geocaching (and letterboxing) in Sunday's Ark DemGaz. It was in the "Taking it Outside" section.
They didn't go into any great detail, but they did do a good job of giving the basic idea of what geocaching is and how it is done.
This got me thinking. I was told about caching by a good friend who heard about it from another person. I have told numerous people about the sport and had some show real interest in what we do. However, I don't know of anyone who read an article, heard about it on the news, or some other noninterpersonal interaction, and is now an avid cacher.
I'm curious to know, how did you other cachers get involved in this hobby (aka addiction)? Did you read about it and decide that this was for you?
