Following their previous episode which discussed the Geocaching MB, I sent a note to Art and Karen, the hosts of the Centennial State Geocaching podcast and scouters, about the concerns I had over BSA's new Geocaching Merit Badge being specific to Groundspeak. Karen read my letter on this week's episode and followed that by speaking extensively about the two other main caching sites, TerraCaching and Navicache.
If you're a geocacher, I recommend subscribing to their podcast, but in either case, I'd urge you this to follow the links below to listen to these two episodes show. You can also leave comments on the page.
