On Ask About Fly Fishing Internet Radio, which is a site with a rather unfortunate title, in my opinion.
My favorite part was when the host used the term "diddle dallee" (not sure I spelled that correctly). A lot of what Craig talks about is old hat to folks around the region (like when the host asks about the location of YNP), so you may be better off downloading and fast forwarding. While most of the talk centers around YNP, there is some good info but you have be patient or hunt for it. Its always worth listening to one of the giants of local fly fishing community, in my opinion.
Give it a listen.
