Good suggestion, Doc.
It gives people here some "connection" while not bogging K&B down so much.
I know, that sounds weird, like we are "the great unwashed" or something, but it isn't what I mean. The air time is precious, too, and doing it this way lets them choose topics they can prepare for, and find of interest.
I don't need them to find me a psychic to locate a lost puppy, and I doubt many folk would want to listen to them politely beg off the job from others, either...
Ok, I'm diggin the hole deeper here, methinks.
You know what I mean, damnit!!
