For a large chunk of Pete's career, radio was just about the only option for folks outside central Iowa. Football was on TV about once per year, home basketball was on WOI (and not much else), and the Saturday league games were on the syndicated regional "network."
Walters will never get that same sentimental vibe simply because of the myriad of consumer options.
Walters is best if only for the way he takes on sports radio hosts!
