I don't think we've out grown fishing shows, we just need shows that are average joe fisherman doing their thing. I enjoy watching shows from new areas, and love the saltwater shows, but the bass stuff drives me nuts.
The fishing adventurer, fishn canada, adventures north, and the musky hunter are the only ones I really "try" to tune into. I'll watch bob izumi if he's on and not bass fishing too.
The spin on travel that the fishing adventurer has taken is a great idea, and makes for a great show IMO.
