I'll admit that I had stopped listening to the Chicago Geocacher podcast because it was sufficiently off-topic that it bored me. I didn't know any of the people they talk about. I live in the city, not the suburbs, and they mainly focus on the suburbs (Sorry, guys, Palatine and Arlington Heights are not Chicago). Mostly, I just wanted them to stay on topic - give me actual geocaching content!
Then, I started getting more "involved" with the local community and I've had a change of heart. Now I know where Joliet is. Now I know who Ziggy is. Heck, now I've even met the hosts. And I realized that the analogy is quite correct - CGP isn't exactly just about geocaching. It's the CarTalk of Geocaching - except with more swearing.
If you want wholesome, listen to Podcacher. If you want informative about the hobby, there are podcasts to that too. If you want two guys having a great deal of fun, being irreverent, and talking a bit about geocaching and they see it - well, you can't beat the Chicago Geocacher podcast.
