I heard the podcast! That's partly why I'm here now! I love the idea of geocaching, altho my first hunt was a disaster. Looking for some more tomorrow, a bit more hopeful and already really excited about placing some of my own, so have been looking up tips and what people like and what not.
Also I think a month or two ago someone wrote in to the Kermode and Mayo Film Review about geocaching, something about wanting a signed picture to put in a cache, did anyone hear that one? I didn't really know what GC was at the time, so I may be mis-remembering.
