For those following this or curious. I didn't find a way to batch download them. Basically I found about 40 episodes and searched via source code to find the mp3 and downloaded those 1 by 1
Wow. I tried searching for Garden Talk RSS and got a different show, added WTIC to it and the only accurate hit was literally this thread right here LOL
Anyway, I did a little poking around, and I noticed that every episode I clicked on said "This episode is not available" leading me to believe that they've been removed from their servers. You may be SOL here.
We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.
