I listen to podcasts on my Ipod.
You can go to the iTunes store and search for "fly fishing podcast". There are many choices and you can subscribe to them. As they are released, they will be downloaded into itunes and you can then choose to load them onto your iPod by choosing them under the "podcast" menu when you attach your iPod.
For me, it is more convenient to create a Podcast playlist. I call mine "New Podcasts" and I individually load and arrange the podcasts in the order I want to listen to them. After I listen to them, I remove them.
My favorite podcast is "Ask About Fly Fishing Podcast". You can search for it in the search window at the iTunes Store.
You can go to the site here and see what they have:

Another on is the Itinerant Angler Podcast. Same subscription method on iTunes and here is the site:
