Two days later, somebody in Seattle hid a container of goodies, and posted satellite coordinates of where it could be found. Another guy found the goodies and up went a Web site about it, later posted to the sci.geo.satellite-nav newsgroup. Today, according to the site, there are 194,813 active caches (or hidden goodies) in 217 countries.
I've heard about this, but didn't realize it was so popular. Nice, sounds like fun.
