The other day I ran across a great podcast called, Podcacher. As of this week, they are up to 76 shows. Sonny and Sandy put on a great show with all sorts of Geocaching related information.
Their podcast is the most professional sounding non-professional podcast I’ve heard. (Even before their latest equipment donations!) If you search iTMS for “Podcacher” it’ll come up. Or head over to their blog and check out the Forums.
